In the previous article, we have discussed Python Program to Find sum of Even Factors of a Number
Given a number, and the task is to get the sum of odd factors of a given number.

Factors are numbers or algebraic expressions that divide another number by themselves and leave no remainder.

Example: let the given number = 24

# The factors of 24 are : 1, 2, 3, 4, 6, 8, 12, 24

The sum of odd factors of 24 = 1+3= 4

Examples:

Example1:

Input:

Given Number = 24

Output:

The Sum of all odd factors of { 24 }  =  4

Example2:

Input:

Given Number = 72

Output:

The Sum of all odd factors of { 72 }  =  13

Program to Find the Sum of Odd Factors of a Number in Python

Below are the ways to the sum of odd factors of a given number.

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

Method #1: Using For Loop (Static Input)

Approach:

• Give the number as static input and store it in a variable.
• Take an empty list and store it in another variable.
• Loop from ‘1’  to the above-given number range using For loop.
• Check whether the given number modulus iterator value is equal to ‘0’ or not using the if conditional statement.
• If the statement is True, Check if the iterator modulus 2 is not equal to 0 using the if conditional statement.
• If the statement is True, append the iterator value to the above-declared list.
• Get the sum of all odd factors of the above-given list using the built-in sum() function and store it in another variable.
• Print the sum of all the odd factors of a given number.
• The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numb = 24
# Take an empty list and store it in another variable.
all_factors = []
# Loop from '1' to above given number range using For loop.
for itr in range(1, gvn_numb+1):
    # Check whether the given number modulus iterator value is equal to '0' or not
    # using if conditional statement.
    if gvn_numb % itr == 0:
        # If the statement is True, Check if the iterator modulus 2 is not equal to 0 using the
        # if conditional statement.
        if itr % 2 != 0:
            # If the statement is True ,append the iterator value to the above declared list .
            all_factors.append(itr)
      # Get the sum of all the odd factors of above got list using built-in sum() function
      # and store it in another variable.
reslt = sum(all_factors)
# Print the sum of all odd factors of a given number.
print("The Sum of all odd factors of {", gvn_numb, "}  = ", reslt)

Output:

The Sum of all odd factors of { 24 }  =  4

Method #2: Using For loop (User Input)

Approach:

• Give the number as user input using int(input()) and store it in a variable.
• Take an empty list and store it in another variable.
• Loop from ‘1’  to the above-given number range using For loop.
• Check whether the given number modulus iterator value is equal to ‘0’ or not using the if conditional statement.
• If the statement is True, Check if the iterator modulus 2 is not equal to 0 using the if conditional statement.
• If the statement is True, append the iterator value to the above-declared list.
• Get the sum of all odd factors of the above-given list using the built-in sum() function and store it in another variable.
• Print the sum of all the odd factors of a given number.
• The Exit of the program.

Below is the implementation:

# Give the number as user input using int(input()) and store it in a variable.
gvn_numb = int(input("Enter some random Number = "))
# Take an empty list and store it in another variable.
all_factors = []
# Loop from '1' to above given number range using For loop.
for itr in range(1, gvn_numb+1):
    # Check whether the given number modulus iterator value is equal to '0' or not
    # using if conditional statement.
    if gvn_numb % itr == 0:
# If the statement is True, Check if the iterator modulus 2 is not equal to 0 using the
# if conditional statement.
        if itr % 2 != 0:
            # If the statement is True ,append the iterator value to the above declared list .
            all_factors.append(itr)
# Get the sum of all the odd factors of above got list using built-in sum() function
# and store it in another variable.
reslt = sum(all_factors)
# Print the sum of all odd factors of a given number.
print("The Sum of all odd factors of {", gvn_numb, "}  = ", reslt)

Output:

Enter some random Number = 56
The Sum of all odd factors of { 56 } = 8

In the previous article, we have discussed Python Program for Maximum Distance between Two Occurrences of Same Element in Array/List
Given a list and the task is to check to see if the given list can be sorted with a single swap.

copy() method:

The list’s shallow copy is returned by the copy() method.

There are no parameters to the copy() method.

It creates a new list. It makes no changes to the original list.

Examples:

Example1:

Input:

Given List = [7, 8, 9]

Output:

The given list [7, 8, 9] can be sorted with a single swap

Explanation:

When we swap 7 and 9 we get [9, 8, 7] which is a sorted list.

Example2:

Input:

Given List = [6, 3, 2, 1]

Output:

The given list [6, 3, 2, 1] cannot be sorted with a single swap

Program to Check if Array can be Sorted with One Swap in Python:

Below are the ways to check to see if the given list can be sorted with a single swap.

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

Method #1: Using For Loop (Static Input)

Approach:

• Give the list as static input and store it in a variable.
• Copy the given list in a variable say “new_lst” using the copy() function.
• Take a variable say ‘c’ and initialize its value with 0.
• Sort the above obtained “new_lst”.
• Loop until the length of the “new_lst” using the for loop.
• Check if the given list element is not equal to the new_lst element using the if conditional statement.
• If the statement is true then increment the count value of ‘c’ by 1 and store it in the same variable ‘c‘.
• Check if the value of ‘c’ is equal to 0 or true using the if conditional statement and ‘or ‘ keyword.
• If the statement is true, print “The given list can be sorted with a single swap”.
• If it is false, then print “The given list cannot be sorted with a single swap”.
• The Exit of the Program.

Below is the implementation:

# Give the list as static input and store it in a variable.
gven_lst = [7, 8, 9]
# Copy the given list in a variable say "new_lst" using the copy() function.
new_lst = gven_lst.copy()
# Take a variable say 'c' and initialize its value with 0.
c = 0
# Sort the above obtained "new_lst".
new_lst.sort()
# Loop until the length of the "new_lst" using the for loop.
for i in range(len(new_lst)):
 # Check if the given list element is not equal to the new_lst element using the
    # if conditional statement.
    if(gven_lst[i] != new_lst[i]):
     # If the statement is true then increment the count value of 'c' by 1 and
        # store it in the same variable 'c'.
        c += 1
# Check if the value of 'c' is equal to 0 or true using the if conditional statement
# and 'or ' keyword.
if(c == 0 or c == 2):
  # If the statement is true, print "The given list can be sorted with a single swap".
    print("The given list", gven_lst, "can be sorted with a single swap")
 # If it is false, then print "The given list cannot be sorted with a single swap".
else:
    print("The given list", gven_lst, "cannot be sorted with a single swap")

Output:

The given list [7, 8, 9] can be sorted with a single swap

Method #2: Using For loop (User Input)

Approach:

• Give the list as user input using list(),map(),input(),and split() functions.
• Store it in a variable.
• Copy the given list in a variable say “new_lst” using the copy() function.
• Take a variable say ‘c’ and initialize its value with 0.
• Sort the above obtained “new_lst”.
• Loop until the length of the “new_lst” using the for loop.
• Check if the given list element is not equal to the new_lst element using the if conditional statement.
• If the statement is true then increment the count value of ‘c’ by 1 and store it in the same variable ‘c‘.
• Check if the value of ‘c’ is equal to 0 or true using the if conditional statement and ‘or ‘ keyword.
• If the statement is true, print “The given list can be sorted with a single swap”.
• If it is false, then print “The given list cannot be sorted with a single swap”.
• The Exit of the Program.

Below is the implementation:

# Give the list as user input using list(),map(),input(),and split() functions.
#Store it in a variable.
gven_lst = list(map(int, input(
   'Enter some random List Elements separated by spaces = ').split()))
# Copy the given list in a variable say "new_lst" using the copy() function.
new_lst = gven_lst.copy()
# Take a variable say 'c' and initialize its value with 0.
c = 0
# Sort the above obtained "new_lst".
new_lst.sort()
# Loop until the length of the "new_lst" using the for loop.
for i in range(len(new_lst)):
 # Check if the given list element is not equal to the new_lst element using the
    # if conditional statement.
    if(gven_lst[i] != new_lst[i]):
     # If the statement is true then increment the count value of 'c' by 1 and
        # store it in the same variable 'c'.
        c += 1
# Check if the value of 'c' is equal to 0 or true using the if conditional statement
# and 'or ' keyword.
if(c == 0 or c == 2):
  # If the statement is true, print "The given list can be sorted with a single swap".
    print("The given list", gven_lst, "can be sorted with a single swap")
 # If it is false, then print "The given list cannot be sorted with a single swap".

    print("The given list", gven_lst, "cannot be sorted with a single swap")

Output:

Enter some random List Elements separated by spaces = 5 6 7 12 15
The given list [5, 6, 7, 12, 15] can be sorted with a single swap

Dictionaries:

Python dictionaries are mutable collections of things that contain key-value pairs. The dictionary contains two main components: keys and values. These keys must be single elements, and the values can be of any data type, such as list, string, integer, tuple, and so on. The keys are linked to their corresponding values. In other words, the values can be retrieved using their corresponding keys.

A dictionary is created in Python by enclosing numerous key-value pairs in curly braces.

Given a list, the task is to find the greatest distance between two occurrences of an element in a given list of repeated elements.

Examples:

Example1:

Input:

Given List =  [1, 2, 3, 7, 8, 9, 2, 1, 4, 3]

Output:

The greatest distance between two occurrences of an element in a given list of repeated elements = 7

Example2:

Input:

Given List = [6, 7, 8, 2, 1, 6, 8, 9]

Output:

The greatest distance between two occurrences of an element in a given list of repeated elements = 5

Program for Maximum Distance between Two Occurrences of the Same Element in Array/List in Python

Below are the ways to find the greatest distance between two occurrences of an element in a given list of repeated elements:

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

Method #1: Using For Loop (Static Input)

Approach:

• Give the list as static input and store it in a variable.
• Calculate the length of the given list using the len() function and store it in another variable.
• Create an empty dictionary and store it in another variable.
• Take a variable say “max_val” and initialize its value with 0.
• Loop till the number of elements of the list using the for loop.
• Check if the list element is present in the dictionary keys or not using the if conditional statement.
• If the statement is true, then update the dictionary with the key as a list element and value as an iterator.
• If it is not true, calculate the maximum value of “max_val” and iterator -dictionary of list of iterator and store it in “max_val”.
• Print “max_val” to get the greatest distance between two occurrences of an element in a given list of repeated elements.
• The Exit of the Program.

Below is the implementation:

# Give the list as static input and store it in a variable.
gvn_lst = [1, 2, 3, 7, 8, 9, 2, 1, 4, 3]
# Calculate the length of the given list using the len() function and store it in
# another variable.
lst_len = len(gvn_lst)
# Create an empty dictionary and store it in another variable.
new_dict = {}
# Take a variable say "max_val" and initialize its value with 0.
max_val = 0
# Loop till the number of elements of the list using the for loop.
for itr in range(lst_len):
    # Check if the list element is present in the dictionary keys or not using the
    # if conditional statement.
    if gvn_lst[itr] not in new_dict.keys():
        # If the statement is true, then update the dictionary with the key as a list element
        # and value as an iterator.
        new_dict[gvn_lst[itr]] = itr
 # If it is not true, calculate the maximum value of "max_val" and iterator -dictionary
# of list of iterator and store it in "max_val".
    else:
        max_val = max(max_val, itr-new_dict[gvn_lst[itr]])
 # Print "max_val" to get the greatest distance between two occurrences of an element
# in a given list of repeated elements.
print("The greatest distance between two occurrences of an element in a given list of repeated elements = ", max_val)

Output:

The greatest distance between two occurrences of an element in a given list of repeated elements =  7

Method #2: Using For loop (User Input)

Approach:

• Give the list as user input using list(),map(),input(),and split() functions.
• Store it in a variable.
• Calculate the length of the given list using the len() function and store it in another variable.
• Create an empty dictionary and store it in another variable.
• Take a variable say “max_val” and initialize its value with 0.
• Loop till the number of elements of the list using the for loop.
• Check if the list element is present in the dictionary keys or not using the if conditional statement.
• If the statement is true, then update the dictionary with the key as a list element and value as an iterator.
• If it is not true, calculate the maximum value of “max_val” and iterator -dictionary of list of iterator and store it in “max_val”.
• Print “max_val” to get the greatest distance between two occurrences of an element in a given list of repeated elements.
• The Exit of the Program.

Below is the implementation:

# Give the list as user input using list(),map(),input(),and split() functions.
#Store it in a variable.
gvn_lst = list(map(int, input(
   'Enter some random List Elements separated by spaces = ').split()))
# Calculate the length of the given list using the len() function and store it in
# another variable.
lst_len = len(gvn_lst)
# Create an empty dictionary and store it in another variable.
new_dict = {}
# Take a variable say "max_val" and initialize its value with 0.
max_val = 0
# Loop till the number of elements of the list using the for loop.
for itr in range(lst_len):
    # Check if the list element is present in the dictionary keys or not using the
    # if conditional statement.
    if gvn_lst[itr] not in new_dict.keys():
        # If the statement is true, then update the dictionary with the key as a list element
        # and value as an iterator.
        new_dict[gvn_lst[itr]] = itr
 # If it is not true, calculate the maximum value of "max_val" and iterator -dictionary
# of list of iterator and store it in "max_val".
    else:
        max_val = max(max_val, itr-new_dict[gvn_lst[itr]])
 # Print "max_val" to get the greatest distance between two occurrences of an element
# in a given list of repeated elements.
print("The greatest distance between two occurrences of an element in a given list of repeated elements = ", max_val)

Output:

Enter some random List Elements separated by spaces = 6 7 8 2 1 6 8 9
The greatest distance between two occurrences of an element in a given list of repeated elements = 5

Highest Common Factor (HCF) / Greatest Common Divisor (GCD) :

When at least one of the integers is not zero, the greatest positive integer that evenly divides the numbers without a remainder is called the Highest Common Factor or Greatest Common Divisor.

The GCD of 12 and 16 is, for example, 4.

Given two numbers, n, and m, and the task is to solve the equation, Find the largest integer a(gcd) that is divisible by all integers n, n + 1, n + 2,…, m.

We only need to look at two cases here:

If a = b, the segment is made up of a single number, so the answer is a.
If a = b, then gcd(n, n + 1, n?+ 2,…, m) = gcd(n, n + 1), n + 2,…, m) = gcd(1, n + 2,…, n) = 1.

Examples:

Example1:

Input:

Given First Number =   125
Given Second Number = 125

Output:

The greatest number that divides both 125 and 125 = 125

Example2:

Input:

Given First Number = 5
Given Second Number = 8

Output:

The greatest number that divides both 5 and 8 = 1

Program to Find GCD of Elements in a Given Range in Python.
