Given the lower limit range and upper limit range, the task is to print all Co-binary Palindromic Numbers in the given range in Python.

Co-binary Palindromic Numbers:

A co-binary palindrome is a number that is a palindrome both as a decimal number and after being binary transformed.

Examples:

Example1:

Input:

Given upper limit range =11
Given lower limit range =2426

Output:

The Co-binary palindrome numbers in the given range 11 and 2426 are:
33 99 313 585 717

Example2:

Input:

Given upper limit range =5
Given lower limit range =12564

Output:

The Co-binary palindrome numbers in the given range 5 and 12564 are:
5 7 9 33 99 313 585 717 7447 9009

Program to Print All Co-binary Palindromic Numbers in a Range in

Python

Below are the ways to print all Co-binary Palindromic Numbers in the given range in Python.

• Using For loop(Static Input)
• Using For loop(User Input)

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Method #1: Using For Loop (Static Input)

Approach:

• Give the lower limit range as static input and store it in a variable.
• Give the upper limit range as static input and store it in another variable.
• Create a function checkpalindromicNumb() which accepts the string as an argument and returns true if the string is palindrome else it returns False.
• Create a function convertBinar() which converts the given number to binary and returns it.
• Loop from lower limit range to upper limit range using For loop.
• Convert this iterator value to binary by passing it as an argument to convertBinar() function and store it in a variable say binarystrng.
• Convert this iterator value to a string using the str() function say strngnumb.
• Check if the strngnumb is palindrome or not by giving the given strngnumb as an argument to checkpalindromicNumb().
• Check if the binarystrng is palindrome or not by giving the given binarystrng as an argument to checkpalindromicNumb().
• Check if both statements are true using the and operator and If conditional Statement.
• If it is true then print it.
• The Exit of the Program.

Below is the implementation:

# Create a function checkpalindromicNumb() which accepts the string as an argument and
# returns true if the string is palindrome else it returns False.
def checkpalindromicNumb(val):
    return val == val[::-1]
# Create a function convertBinar() which converts the given number to binary and returns it.
def convertBinar(orinumb):
    return bin(orinumb)[2:]
# Give the lower limit range as static input and store it in a variable.
lowlimrange = 11
# Give the upper limit range as static input and store it in another variable.
upplimrange = 2426
print('The Co-binary palindrome numbers in the given range',
      lowlimrange, 'and', upplimrange, 'are:')
# Loop from lower limit range to upper limit range using For loop.
for itervalu in range(lowlimrange, upplimrange+1):
    # Convert this iterator value to binary by passing it as an argument
    # to convertBinar() function and store it in a variable say binarystrng.
    binarystrng = convertBinar(itervalu)
    # Convert this iterator value to a string
    # using the str() function say strngnumb.
    strngnumb = str(itervalu)
    # Check if the strngnumb is palindrome or not by giving the given strngnumb
    # as an argument to checkpalindromicNumb().
    # Check if the binarystrng is palindrome or not by giving the given binarystrng
    # as an argument to checkpalindromicNumb().
    # Check if both statements are true using the and operator and If conditional Statement.
    if(checkpalindromicNumb(binarystrng) and checkpalindromicNumb(strngnumb)):
        # If it is true then print it.
        print(strngnumb, end=' ')

Output:

The Co-binary palindrome numbers in the given range 11 and 2426 are:
33 99 313 585 717

Method #2: Using For Loop (User Input)

Approach:

• Give the lower limit range and upper limit range as user input using map(),int(),split() functions.
• Store them in two separate variables.
• Create a function checkpalindromicNumb() which accepts the string as an argument and returns true if the string is palindrome else it returns False.
• Create a function convertBinar() which converts the given number to binary and returns it.
• Loop from lower limit range to upper limit range using For loop.
• Convert this iterator value to binary by passing it as an argument to convertBinar() function and store it in a variable say binarystrng.
• Convert this iterator value to a string using the str() function say strngnumb.
• Check if the strngnumb is palindrome or not by giving the given strngnumb as an argument to checkpalindromicNumb().
• Check if the binarystrng is palindrome or not by giving the given binarystrng as an argument to checkpalindromicNumb().
• Check if both statements are true using the and operator and If conditional Statement.
• If it is true then print it.
• The Exit of the Program.

Below is the implementation:

# Create a function checkpalindromicNumb() which accepts the string as an argument and
# returns true if the string is palindrome else it returns False.
def checkpalindromicNumb(val):
    return val == val[::-1]
# Create a function convertBinar() which converts the given number to binary and returns it.
def convertBinar(orinumb):
    return bin(orinumb)[2:]

# Give the lower limit range and upper limit range as
# user input using map(),int(),split() functions.
# Store them in two separate variables.
lowlimrange, upplimrange = map(int, input(
    'Enter lower limit range and upper limit range separate bt spaces = ').split())
print('The Co-binary palindrome numbers in the given range',
      lowlimrange, 'and', upplimrange, 'are:')
# Loop from lower limit range to upper limit range using For loop.
for itervalu in range(lowlimrange, upplimrange+1):
    # Convert this iterator value to binary by passing it as an argument
    # to convertBinar() function and store it in a variable say binarystrng.
    binarystrng = convertBinar(itervalu)
    # Convert this iterator value to a string
    # using the str() function say strngnumb.
    strngnumb = str(itervalu)
    # Check if the strngnumb is palindrome or not by giving the given strngnumb
    # as an argument to checkpalindromicNumb().
    # Check if the binarystrng is palindrome or not by giving the given binarystrng
    # as an argument to checkpalindromicNumb().
    # Check if both statements are true using the and operator and If conditional Statement.
    if(checkpalindromicNumb(binarystrng) and checkpalindromicNumb(strngnumb)):
        # If it is true then print it.
        print(strngnumb, end=' ')

Output:

Enter lower limit range and upper limit range separate bt spaces = 5 12564
The Co-binary palindrome numbers in the given range 5 and 12564 are:
5 7 9 33 99 313 585 717 7447 9009

When it comes to programming challenges, bits are really significant. In this post, we looked at how to use Python to determine whether the kth bit of a number is set or not.

Examples:

Example1:

Input:

Given Number =29
Given K=3

Output:

Enter the given number and the value of k separated by spaces = 29 3
The 3 nd bit in the number 29 (binary representation = 11101 ) is set bit

Example2:

Input:

Given Number =576
Given K=3

Output:

The 3 nd bit in the number number 576 (binary representation = 1001000000 )is not a set bit

Program to Check whether kth Bit is Set or not in Python

Below are the ways to check whether the kth bit is set bit or not in python.

• Using Left Shift Operator (Static Input)
• Using Left Shift Operator (User Input)
• Using Right Shift Operator (Static Input)
• Using Right Shift Operator (User Input)

Are you wondering how to seek help from subject matter experts and learn the Java language? Go with these Basic Java Programming Examples and try to code all of them on your own then check with the exact code provided by expert programmers.

Method #1: Using Left Shift Operator (Static Input)

Approach:

• Give the number and the value of k as static input and store it in a variable.
• First, compute 1<<(k-1) and save it in a variable called temp, resulting in temp=1<<(k-1). temp holds an integer with only the kth bit set.
• You must execute a bitwise AND of number and temp in this step. If this gives a non-zero integer, the kth bit of the number is set otherwise, it is not.
• To Check the above statement using the If conditional Statement.
• If it is true then print the kth bit is set bit.
• Else print it is not set bit.
• The Exit of the Program.

Below is the implementation:

# Give the number and the value of k as static input
# and store it in a variable.
numb = 19
k = 2
# First, compute 1<<(k-1) and save it in a variable called temp,
# resulting in temp=1<<(k-1). temp holds an integer with only the kth bit set.
temp = 1 << (k-1)
# You must execute a bitwise AND of number and temp in this step.
# If this gives a non-zero integer, the kth bit of the number is set otherwise, it is not.
# To Check the above statement using the If conditional Statement.
if (numb & temp):
        # If it is true then print the kth bit is set bit.
    print('The', k, 'nd bit in the number ', numb,
          '(binary representation =', bin(numb)[2:], ') is set bit')
# Else print it is not set bit.
else:
    print('The', k, 'nd bit in the number ', numb,
          '(binary representation =', bin(numb)[2:], ')is not a set bit')

Output:

The 2 nd bit in the number 19 (binary representation = 10011 ) is set bit

Method #2: Using Left Shift Operator (User Input)

Approach:

• Give the number and the value of k as user input using map(), int(), split() functions and store them in two separate variables.
• First, compute 1<<(k-1) and save it in a variable called temp, resulting in temp=1<<(k-1). temp holds an integer with only the kth bit set.
• You must execute a bitwise AND of number and temp in this step. If this gives a non-zero integer, the kth bit of the number is set otherwise, it is not.
• To Check the above statement using the If conditional Statement.
• If it is true then print the kth bit is set bit.
• Else print it is not set bit.
• The Exit of the Program.

Below is the implementation:

# Give the number and the value of k as user input using map(), int(), split() functions
# and store them in two separate variables.
numb, k = map(int, input(
    'Enter the given number and the value of k separated by spaces = ').split())
# First, compute 1<<(k-1) and save it in a variable called temp,
# resulting in temp=1<<(k-1). temp holds an integer with only the kth bit set.
temp = 1 << (k-1)
# You must execute a bitwise AND of number and temp in this step.
# If this gives a non-zero integer, the kth bit of the number is set otherwise, it is not.
# To Check the above statement using the If conditional Statement.
if (numb & temp):
        # If it is true then print the kth bit is set bit.
    print('The', k, 'nd bit in the number', numb,
          '(binary representation =', bin(numb)[2:], ') is set bit')
# Else print it is not set bit.
else:
    print('The', k, 'nd bit in the number', numb,
          '(binary representation =', bin(numb)[2:], ')is not a set bit')

Output:

Enter the given number and the value of k separated by spaces = 29 3
The 3 nd bit in the number 29 (binary representation = 11101 ) is set bit

Method #3: Using Right Shift Operator (Static Input)

Approach:

• Give the number and the value of k as static input and store it in a variable.
• First, compute number>>(k-1) and store it in a variable called temp, resulting in temp=number>>(k-1). If the kth bit is set, the last bit of temp will be 1, otherwise, it will be 0.
• You must execute a bitwise AND of 1 and temp in this step. If this gives a non-zero integer, the kth bit of the number is set, otherwise, it is not.
• To Check the above statement using the If conditional Statement.
• If it is true then print the kth bit is set bit.
• Else print it is not set bit.
• The Exit of the Program.

Below is the implementation:

# Give the number and the value of k as static input # and store it in a variable.
numb = 19
k = 2
# First, compute number>>(k-1) and store it in a variable called temp, resulting in temp=number>>(k-1).
# If the kth bit is set, the last bit of temp will be 1, otherwise, it will be 0.
temp = numb >> (k-1)
# You must execute a bitwise AND of 1 and temp in this step.
# If this gives a non-zero integer,
# the kth bit of the number is set, otherwise, it is not.
if (1 & temp):
        # If it is true then print the kth bit is set bit.
    print('The', k, 'nd bit in the number ', numb,
          '(binary representation =', bin(numb)[2:], ') is set bit')
# Else print it is not set bit.
else:
    print('The', k, 'nd bit in the number', numb,
          '(binary representation =', bin(numb)[2:], ')is not a set bit')

Output:

The 2 nd bit in the number 19 (binary representation = 10011 ) is set bit

Method #4: Using Right Shift Operator (User Input)

Approach:

• Give the number and the value of k as user input using map(), int(), split() functions and store them in two separate variables.
• First, compute number>>(k-1) and store it in a variable called temp, resulting in temp=number>>(k-1). If the kth bit is set, the last bit of temp will be 1, otherwise, it will be 0.
• You must execute a bitwise AND of 1 and temp in this step. If this gives a non-zero integer, the kth bit of the number is set, otherwise, it is not.
• To Check the above statement using the If conditional Statement.
• If it is true then print the kth bit is set bit.
• Else print it is not set bit.
• The Exit of the Program.

# Give the number and the value of k as user input using map(), int(), split() functions
# and store them in two separate variables.
numb, k = map(int, input(
    'Enter the given number and the value of k separated by spaces = ').split())
# First, compute number>>(k-1) and store it in a variable called temp, resulting in temp=number>>(k-1).
# If the kth bit is set, the last bit of temp will be 1, otherwise, it will be 0.
temp = numb >> (k-1)
# You must execute a bitwise AND of 1 and temp in this step.
# If this gives a non-zero integer,
# the kth bit of the number is set, otherwise, it is not.
if (1 & temp):
        # If it is true then print the kth bit is set bit.
    print('The', k, 'nd bit in the number', numb,
          '(binary representation =', bin(numb)[2:], ') is set bit')
# Else print it is not set bit.
else:
    print('The', k, 'nd bit in the number', numb,
          '(binary representation =', bin(numb)[2:], ')is not a set bit')

• Give the lower limit range as static input and store it in a variable.
• Give the upper limit range as static input and store it in another variable.

• Inside the for loop pass the iterator value to checkharshadnumb() function.
• If it returns true then print the iterator value.
• Inside the checkharshadnumb() function.
• Make a copy of the number(argument) so you can verify the outcome later.
• Make a result variable ( set to 0 ).
• Create a while loop to go digit by digit through the number.

Given a string, the task is to check whether the given string contains all the unique characters in Python.

Examples:

Example1:

Input:

Given string =btech

Output:

The given string [ btech ] contains unique characters

Example2:

The given string [ bteceeh ] contains duplicate characters

Program to Check whether String Contains Unique Characters in Python

Below are the ways to check whether the given string contains unique characters in python.

• Using Counter() (Hashing , Static Input)
• Using Counter() (Hashing , User Input)
• Using set() method (Static Input)
• Using set() method (User Input)

Explore complete java concepts from the Java programming examples and get ready to become a good programmer and crack the java software developer interview with ease.

Method #1: Using Counter() (Hashing , Static Input)

Approach:

• Import the Counter() function from collections using the import keyword.
• Give the string as static input and store it in a variable.
• Calculate the frequency of all the given string elements using the Counter() function which returns the element and its frequency as key-value pair and store this dictionary in a variable(say strngfreqelements)
• Calculate the length of this frequency dictionary using the len() function and store it in a variable.
• Calculate the length of the given string using the len() function and store it in another variable.
• Check if both lengths are equal or not using the If conditional statement.
• If both lengths are equal then the given string contains all the unique characters.
• Else the given string contains duplicate characters.
• The Exit of the program.

Below is the implementation:

# Import the Counter() function from collections using the import keyword.
from collections import Counter
# Give the string as static input and store it in a variable.
givenstrng = 'btech'
# Calculate the frequency of all the given string elements
# using the Counter() function which returns the element
# and its frequency as key-value pair and
# store this dictionary in a variable(say strngfreqelements)
strngfreqelements = Counter(givenstrng)
# Calculate the length of this frequency dictionary
# using the len() function and store it in a variable.
lengthfreq = len(strngfreqelements)
# Calculate the length of the given string using
# the len() function and store it in another variable.
lengthstrng = len(givenstrng)
# Check if both lengths are equal or not using the If conditional statement.
# If both lengths are equal then the given string contains all the unique characters.
if(lengthfreq == lengthstrng):
    print('The given string [', givenstrng, '] contains unique characters')
# Else the given string contains duplicate characters.
else:
    print('The given string [', givenstrng, '] contains duplicate characters')

Output:

The given string [ btech ] contains unique characters

Method #2: Using Counter() (Hashing , User Input)

Approach:

• Import the Counter() function from collections using the import keyword.
• Give the string as user input using the input() function and store it in a variable.
• Calculate the frequency of all the given string elements using the Counter() function which returns the element and its frequency as key-value pair and store this dictionary in a variable(say strngfreqelements)
• Calculate the length of this frequency dictionary using the len() function and store it in a variable.
• Calculate the length of the given string using the len() function and store it in another variable.
• Check if both lengths are equal or not using the If conditional statement.
• If both lengths are equal then the given string contains all the unique characters.
• Else the given string contains duplicate characters.
• The Exit of the program.

Below is the implementation:

# Import the Counter() function from collections using the import keyword.
from collections import Counter
# Give the string as user input using the input() function and store it in a variable.
givenstrng = input('Enter some random string = ')
# Calculate the frequency of all the given string elements
# using the Counter() function which returns the element
# and its frequency as key-value pair and
# store this dictionary in a variable(say strngfreqelements)
strngfreqelements = Counter(givenstrng)
# Calculate the length of this frequency dictionary
# using the len() function and store it in a variable.
lengthfreq = len(strngfreqelements)
# Calculate the length of the given string using
# the len() function and store it in another variable.
lengthstrng = len(givenstrng)
# Check if both lengths are equal or not using the If conditional statement.
# If both lengths are equal then the given string contains all the unique characters.
if(lengthfreq == lengthstrng):
    print('The given string [', givenstrng, '] contains unique characters')
# Else the given string contains duplicate characters.
else:
    print('The given string [', givenstrng, '] contains duplicate characters')

Output:

Enter some random string = oneplus
The given string [ oneplus ] contains unique characters

Method #3: Using set() method (Static Input)

Approach:

• Give the string as static input and store it in a variable.
• Convert this string to set using set() function and store it in a variable.
• Calculate the length of this set using the len() function and store it in a variable.
• Calculate the length of the given string using the len() function and store it in another variable.
• Check if both lengths are equal or not using the If conditional statement.
• If both lengths are equal then the given string contains all the unique characters.
• Else the given string contains duplicate characters.
• The Exit of the program.

Below is the implementation:

# Give the string as static input and store it in a variable.
givenstrng = 'bteceeh'
# Convert this string to set using set() function and store it in a variable.
strngset = set(givenstrng)
# Calculate the length of this set using the len() function and store it in a variable.
lengthfreq = len(strngset)
# Calculate the length of the given string using
# the len() function and store it in another variable.
lengthstrng = len(givenstrng)
# Check if both lengths are equal or not using the If conditional statement.
# If both lengths are equal then the given string contains all the unique characters.
if(lengthfreq == lengthstrng):
    print('The given string [', givenstrng, '] contains unique characters')
# Else the given string contains duplicate characters.
else:
    print('The given string [', givenstrng, '] contains duplicate characters')

Output:

The given string [ bteceeh ] contains duplicate characters

Method #4: Using set() method (User Input)

Approach:

• Give the string as static input and store it in a variable.
• Give the string as user input using the input() function and store it in a variable.
• Calculate the length of this set using the len() function and store it in a variable.
• Calculate the length of the given string using the len() function and store it in another variable.
• Check if both lengths are equal or not using the If conditional statement.
• If both lengths are equal then the given string contains all the unique characters.
• Else the given string contains duplicate characters.
• The Exit of the program.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
givenstrng = input('Enter some random string = ')
# Convert this string to set using set() function and store it in a variable.
strngset = set(givenstrng)
# Calculate the length of this set using the len() function and store it in a variable.
lengthfreq = len(strngset)
# Calculate the length of the given string using
# the len() function and store it in another variable.
lengthstrng = len(givenstrng)
# Check if both lengths are equal or not using the If conditional statement.
# If both lengths are equal then the given string contains all the unique characters.
if(lengthfreq == lengthstrng):
    print('The given string [', givenstrng, '] contains unique characters')
# Else the given string contains duplicate characters.
else:
    print('The given string [', givenstrng, '] contains duplicate characters')

Program to Sort the List According to the Second Element in Sub list in Python

Below are the ways to sort the given list of lists according to the second element in sub list in python some of them are:

• Using nested loops and temporary variable(Static Input)
• Using nested loops and temporary variable(User Input)

Method #1: Using nested loops and temporary variable(Static Input)

Approach:

• Take in a list that contains sublists as static input.
• Using two for loops, sort the sublists using bubble sort based on the second value of the sublist.
• If the second element of the first sublist is greater than the second element of the second sublist, the complete sublist should be exchanged/swapped.
• The sorted list should be printed.
• Exit of program.

Below is the implementation:

# Take in a list that contains sublists as static input.
nestedList = [['hello', 46], ['this', 31], ['morning', 29],
              ['is', 26], ['btechGeeks', 19], ['online', 33]]
# printing the sorted nested list before sorting
print('printing the sorted nested list before sorting :')
print(nestedList)
# Using two for loops, sort the sublists using bubble
# sort based on the second value of the sublist.
for m in range(len(nestedList)):
    for n in range(len(nestedList)-m-1):
      # If the second element of the first sublist is greater than the second element of the second sublist,
      # the complete sublist should be exchanged/swapped using temporary variable
        if(nestedList[n][1] > nestedList[n+1][1]):
            tempo = nestedList[n]
            nestedList[n] = nestedList[n+1]
            nestedList[n+1] = tempo
# printing the sorted nested list after sorting
print('printing the sorted nested list after sorting :')
print(nestedList)

Output:

printing the sorted nested list before sorting :
[['hello', 46], ['this', 31], ['morning', 29], ['is', 26], ['btechGeeks', 19], ['online', 33]]
printing the sorted nested list after sorting :
[['btechGeeks', 19], ['is', 26], ['morning', 29], ['this', 31], ['online', 33], ['hello', 46]]

Method #2: Using nested loops and temporary variable(User Input)

Approach:

• Take a empty list.
• Scan the number of elements /number of sublists as user input using int(input()) function.
• Loop from 1 to given number of elements times using for loop.
• Scan the list elements using input() and int(input()) functions and append to the empty list using append() function.
• Using two for loops, sort the sublists using bubble sort based on the second value of the sublist.
• If the second element of the first sublist is greater than the second element of the second sublist, the complete sublist should be exchanged/swapped.
• The sorted list should be printed.
• Exit of program.

Below is the implementation:

# Take a empty list.
nestedList = []
# Scan the number of elements /number of sublists as user input using int(input()) function.
totalsublists = int(input('Enter some random number of sublists ='))
# Loop from 1 to given number of elements times using for loop.
for r in range(totalsublists):
    # Scan the list elements using input() and int(input()) functions and append
    # to the empty list using append() function.
    firsteleme = input('Enter some random first element =')
    secondeleme = int(input('Enter some random second element ='))
    nestedList.append([firsteleme, secondeleme])

# printing the sorted nested list before sorting
print('printing the sorted nested list before sorting :')
print(nestedList)
# Using two for loops, sort the sublists using bubble
# sort based on the second value of the sublist.
for m in range(len(nestedList)):
    for n in range(len(nestedList)-m-1):
      # If the second element of the first sublist is greater than the second element of the second sublist,
      # the complete sublist should be exchanged/swapped using temporary variable
        if(nestedList[n][1] > nestedList[n+1][1]):
            tempo = nestedList[n]
            nestedList[n] = nestedList[n+1]
            nestedList[n+1] = tempo
# printing the sorted nested list after sorting
print('printing the sorted nested list after sorting :')
print(nestedList)

Output:

Enter some random number of sublists =7
Enter some random first element =hello
Enter some random second element =11
Enter some random first element =this
Enter some random second element =1
Enter some random first element =is
Enter some random second element =23
Enter some random first element =btechgeeks
Enter some random second element =19
Enter some random first element =online
Enter some random second element =39
Enter some random first element =platform
Enter some random second element =7
Enter some random first element =for
Enter some random second element =29
printing the sorted nested list before sorting :
[['hello', 11], ['this', 1], ['is', 23], ['btechgeeks', 19], ['online', 39], ['platform', 7], ['for', 29]]
printing the sorted nested list after sorting :
[['this', 1], ['platform', 7], ['hello', 11], ['btechgeeks', 19], ['is', 23], ['for', 29], ['online', 39]]

Explanation:

• The user must enter a list with numerous sublists.
• Scan the list elements using input() and int(input()) functions and append to the empty list using append() function.
• The list is then sorted using bubble sort based on the second member in the sublist.
• The entire sublist is switched if the second element of the first sublist is bigger than the second element of the second sublist.
• This step is repeated until the full list has been sorted.
• After that, the sorted list is printed.

Strings in Python:

In Python, a string may be a sequence of characters. It is an information type that has been derived. Strings are unchangeable. This means that when they have been defined, they can not be modified. Many Python functions change strings, like replace(), join(), and split(). They do not, however, alter the original string. They make a duplicate of a string, alter it, then return it to the caller.

Given a string, the task is to write a python program to calculate the total number of lowercase characters in the given string.

Examples:

Example1:

Input:

given string = 'Hello this is BTechGeeks'

Output:

The total number of lower case letters present in the given string [ Hello this is BTechGeeks ] =  17

Example2:

Input:

given string = BTechgeeks

Output:

The total number of lower case letters present in the given string [ BTechgeeks ] = 8

Program to Count Number of Lowercase Characters in a String in Python

There are several ways to count the number of lowercase characters in the given string some of them are:

• Using Count Variable and islower() function(Static Input)
• Using Count Variable and islower() function(User Input)
• By Checking Ascii values(Static Input)
• By Checking Ascii values(User Input)

Beginners and experienced programmers can rely on these Best Java Programs Examples and code various basic and complex logics in the Java programming language with ease.

1)Using Count Variable and islower() function(Static Input)

Approach:

• Give the string as static input and save it in a variable.
• Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
• Initialize the countlow to 0.
• Traverse the given string using for loop.
• Check if the iterator value is lowercase or not using islower() function.
• If the character is in lowercase then increment the countlow by 1.
• Print the countlow.

Below is the implementation:

# Give the string as static input and save it in a variable.
given_strng = 'Hello this is BTechGeeks'
# Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
# Initialize the countlow to 0.
countlow = 0
# Traverse the given string using for loop.
for charact in given_strng:
    # Check if the iterator value is lowercase or not using islower() function.
    if(charact.islower()):
        # If the character is in lowercase then increment the countlow by 1.
        countlow = countlow+1
# Print the countlow.
print(
    'The total number of lower case letters present in the given string [', given_strng, '] = ', countlow)

Output:

The total number of lower case letters present in the given string [ Hello this is BTechGeeks ] =  17

2)Using Count Variable and islower() function(User Input)

Approach:

• Give the string as user input using the input() function and store it in a variable.
• Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
• Initialize the countlow to 0.
• Traverse the given string using for loop.
• Check if the iterator value is lowercase or not using islower() function.
• If the character is in lowercase then increment the countlow by 1.
• Print the countlow.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
given_strng = input('Enter some random string = ')
# Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
# Initialize the countlow to 0.
countlow = 0
# Traverse the given string using for loop.
for charact in given_strng:
    # Check if the iterator value is lowercase or not using islower() function.
    if(charact.islower()):
        # If the character is in lowercase then increment the countlow by 1.
        countlow = countlow+1
# Print the countlow.
print('The total number of lower case letters present in the given string [', given_strng, '] = ', countlow)

Output:

Enter some random string = BTechgeeks
The total number of lower case letters present in the given string [ BTechgeeks ] = 8

Explanation:

• A string must be entered by the user and saved in a variable.
• The count variable is set to zero.
• The for loop is used to go over the characters in a string.
• When a lowercase character is encountered, the count is increased.
• The string’s total number of lowercase characters is printed using the print() function.

3)By Checking Ascii values(Static Input)

Approach:

• Give the string as static input and save it in a variable.
• Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
• Initialize the countlow to 0.
• Traverse the given string using for loop.
• Calculate the ASCII value of the character using the ord() function and store it in a variable.
• If the ASCII values lie between 97 to 122 then the character is in lowercase.
• If the character is in lowercase then increment the countlow by 1.
• Print the countlow.

Below is the implementation:

# Give the string as static input and save it in a variable.
given_strng = 'Hello this is BTechGeeks'
# Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
# Initialize the countlow to 0.
countlow = 0
# Traverse the given string using for loop.
for charact in given_strng:
    # Calculate the ASCII value of the character using the ord() function and
    # store it in a variable.
    ascValue = ord(charact)
    # If the ASCII values lie between 97 to 122 then the character is in lowercase.
    if(ascValue >= 97 and ascValue <= 122):
        # If the character is in lowercase then increment the countlow by 1.
        countlow = countlow+1
# Print the countlow.
print(
    'The total number of lower case letters present in the given string [', given_strng, '] = ', countlow)

Output:

The total number of lower case letters present in the given string [ Hello this is BTechGeeks ] =  17

4)By Checking Ascii values(User Input)

Approach:

• Give the string as user input using input() function and save it in a variable.
• Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
• Initialize the countlow to 0.
• Traverse the given string using for loop.
• Calculate the ASCII value of the character using the ord() function and store it in a variable.
• If the ASCII values lie between 97 to 122 then the character is in lowercase.
• If the character is in lowercase then increment the countlow by 1.
• Print the countlow.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
given_strng = input('Enter some random string = ')
# Take a variable to say countlow that stores the total number of lowercase characters present in the given string.
# Initialize the countlow to 0.
countlow = 0
# Traverse the given string using for loop.
for charact in given_strng:
    # Calculate the ASCII value of the character using the ord() function and
    # store it in a variable.
    ascValue = ord(charact)
    # If the ASCII values lie between 97 to 122 then the character is in lowercase.
    if(ascValue >= 97 and ascValue <= 122):
        # If the character is in lowercase then increment the countlow by 1.
        countlow = countlow+1
# Print the countlow.
print(
    'The total number of lower case letters present in the given string [', given_strng, '] = ', countlow)

Output:

Enter some random string = btechGeeks
The total number of lower case letters present in the given string [ btechGeeks ] = 9

Strings in Python:

“String is a character collection or array”

Well in Python too, for the string data type, we say the same definition. The string is a sequenced character array and is written within single, double, or three quotes. Also, Python does not have the data type character, thus it is used as a string of length 1 if we write ‘s’.

Given a hyphen-separated sequence of strings, the task is to sort the strings and print them as hyphen-separated strings in Python.

Examples:

Example1:

Input:

given hyphen-separated string =hello-this-is-btechgeeks

Output:

The string before modification =  hello-this-is-btechgeeks
The string after modification =  btechgeeks-hello-is-this

Example2:

Input:

given hyphen-separated string =good-morning-codechef

Output:

The string before modification = good-morning-codechef
The string after modification = codechef-good-morning

Examples3:

Input:

given hyphen-separated string =btechgeeks-online-platform-fror-coding-students

Output:

The string before modification = btechgeeks-online-platform-fror-coding-students
The string after modification = btechgeeks-coding-fror-online-platform-students

Program to Accept a Hyphen Separated Sequence of Words as Input and Print the Words in a Hyphen-Separated Sequence after Sorting them Alphabetically in Python

Below are the ways to accept a hyphen-separated sequence of strings, the task is to sort the strings and print them as hyphen-separated strings in Python.

• Using split() and join() functions(Static Input)
• Using split() and join() functions(User Input)

Enhancing programming skills is very important no matter what language you have chosen. So, practice frequently with these simple java programs examples and excel in coding the complex logic.

Method #1:Using split() and join() functions(Static Input)

Approach:

• Give the hyphen-separated string as static input and store it in a variable.
• Split the hyphen-separated strings into a list of strings using the split() function and store it in a variable.
• sort the given list using the sort() function.
• Print the sorted sequence by joining the words in the list with a hyphen.
• The Exit of the program.

Below is the implementation of the above approach:

# Give the string as static input and store it in a variable.
givn_strng = 'hello-this-is-btechgeeks'
# print the string before modification
print('The string before modification = ', givn_strng)
# Split the hyphen-separated strings into a list of strings using the split()
# function and store it in a variable.
wordsLis = givn_strng.split('-')
# sort the given list using the sort() function.
wordsLis.sort()
# Print the sorted sequence by joining the words in the list with a hyphen.
resultwords = '-'.join(wordsLis)
# print the resultwords
print('The string after modification = ', resultwords)

Output:

The string before modification =  hello-this-is-btechgeeks
The string after modification =  btechgeeks-hello-is-this

Explanation:

• Give the hyphen-separated string as static input and store it in a variable.
• The hyphen is used as a key to split the sequence, and the words are saved in a list.
• Using the sort() function, the words in the list are sorted alphabetically.
• The terms in the list are then connected together by utilizing a hyphen as a reference.
• The word sequence is then printed in its sorted order.

Method #2:Using split() and join() functions(User Input)

Approach:

• Give the hyphen-separated string as user input using the input() function.
• Split the hyphen-separated strings into a list of strings using the split() function and store it in a variable.
• sort the given list using the sort() function.
• Print the sorted sequence by joining the words in the list with a hyphen.
• The Exit of the program.

Below is the implementation of the above approach:

# Give the hyphen-separated string as user input using the input() function.
givn_strng = input('Enter some random string = ')
# print the string before modification
print('The string before modification = ', givn_strng)
# Split the hyphen-separated strings into a list of strings using the split()
# function and store it in a variable.
wordsLis = givn_strng.split('-')
# sort the given list using the sort() function.
wordsLis.sort()
# Print the sorted sequence by joining the words in the list with a hyphen.
resultwords = '-'.join(wordsLis)
# print the resultwords
print('The string after modification = ', resultwords)

Output:

Enter some random string = good-morning-codechef
The string before modification = good-morning-codechef
The string after modification = codechef-good-morning

Explanation:

• As input, the user must enter a hyphen-separated string of words.
• The hyphen is used as a key to split the sequence, and the words are saved in a list.
• Using the sort() function, the words in the list are sorted alphabetically.
• The terms in the list are then connected together by utilizing a hyphen as a reference.
• The word sequence is then printed in its sorted order.
• It is the fastest and efficient approach.
