Program to Print Multiplication Table using Recursion

Python Program to Print Multiplication Table using Recursion

Python / By

In the previous article, we have discussed Python Program to Find Sum of Even Numbers Using Recursion in a List/Array

Given a number and the task is to print the multiplication table of that number using recursion in python.

Recursion:

Recursion is the process by which a function calls itself directly or indirectly, and the associated function is known as a recursive function. Certain issues can be addressed fairly easily using a recursive approach. Towers of Hanoi (TOH), Inorder /Preorder/Postorder Tree Traversals, DFS of Graph, and other analogous issues are examples.

Examples:

Example1:

Input:

Given Number = 5

Output:

The Multiplication Table of the above given number  5 :
5  X  1  =  5
5  X  2  =  10
5  X  3  =  15
5  X  4  =  20
5  X  5  =  25
5  X  6  =  30
5  X  7  =  35
5  X  8  =  40
5  X  9  =  45
5  X  10  =  50

Example2:

Input:

Given Number = 2

Output:

The Multiplication Table of the above given number  2 :
2  X  1  =  2
2  X  2  =  4
2  X  3  =  6
2  X  4  =  8
2  X  5  =  10
2  X  6  =  12
2  X  7  =  14
2  X  8  =  16
2  X  9  =  18
2  X  10  =  20

Program to Print Multiplication Table using Recursion in Python

Below are the ways to print the multiplication table of the given number using recursion in python:

Method #1: Using Recursion (Static Input)

Approach:

  • Give the number as static input and store it in a variable.
  • Pass the given number and 1 as the arguments to the Mult_table_num function.
  • Create a recursive function to say Mult_table_num which takes the given number and k as the arguments and returns the multiplication table of the given number using recursion.
  • Print the given number multiplied by k.
  • Check if the k value is less than 10 using the if conditional statement.
  • If the statement is true, then pass the given number and k+1 value as the arguments to the Mult_table_num function.{Recursive Logic}
  • Print the multiplication table of the given number using recursion.
  • The Exit of the Program.

Below is the implementation:

# Create a recursive function to say Mult_table_num which takes the given number and k
# as the arguments and returns the multiplication table of the given number
# using recursion.


def Mult_table_num(gven_numb, k):
  # Print the given number multiplied by k.
    print(gven_numb, " X ", k, " = ", gven_numb * k)
    # Check if the k value is less than 10 using the if conditional statement.
    if (k < 10):
      # If the statement is true, then pass the given number and k+1 value as the arguments
      # to the Mult_table_num function.{Recursive Logic}
        Mult_table_num(gven_numb, k + 1)


# Give the number as static input and store it in a variable.
gven_numb = 5
# Print the multiplication table of the given number using recursion.
print("The Multiplication Table of the above given number ", gven_numb, ":")
# Pass the given number and 1 as the arguments to the Mult_table_num function.
Mult_table_num(gven_numb, 1)

Output:

The Multiplication Table of the above given number  5 :
5  X  1  =  5
5  X  2  =  10
5  X  3  =  15
5  X  4  =  20
5  X  5  =  25
5  X  6  =  30
5  X  7  =  35
5  X  8  =  40
5  X  9  =  45
5  X  10  =  50

Method #2: Using Recursion (User Input)

Approach:

  • Give the number as user input using the int(input()) function and store it in a variable.
  • Pass the given number and 1 as the arguments to the Mult_table_num function.
  • Create a recursive function to say Mult_table_num which takes the given number and k as the arguments and returns the multiplication table of the given number using recursion.
  • Print the given number multiplied by k.
  • Check if the k value is less than 10 using the if conditional statement.
  • If the statement is true, then pass the given number and k+1 value as the arguments to the Mult_table_num function.{Recursive Logic}
  • Print the multiplication table of the given number using recursion.
  • The Exit of the Program.

Below is the implementation:

# Create a recursive function to say Mult_table_num which takes the given number and k
# as the arguments and returns the multiplication table of the given number
# using recursion.


def Mult_table_num(gven_numb, k):
  # Print the given number multiplied by k.
    print(gven_numb, " X ", k, " = ", gven_numb * k)
    # Check if the k value is less than 10 using the if conditional statement.
    if (k < 10):
      # If the statement is true, then pass the given number and k+1 value as the arguments
      # to the Mult_table_num function.{Recursive Logic}
        Mult_table_num(gven_numb, k + 1)


# Give the number as user input using the int(input()) function and
# store it in a variable.
gven_numb = int(input("Enter some Random Number = "))
# Print the multiplication table of the given number using recursion.
print("The Multiplication Table of the above given number ", gven_numb, ":")
# Pass the given number and 1 as the arguments to the Mult_table_num function.
Mult_table_num(gven_numb, 1)

Output:

Enter some Random Number = 10
The Multiplication Table of the above given number 10 :
10 X 1 = 10
10 X 2 = 20
10 X 3 = 30
10 X 4 = 40
10 X 5 = 50
10 X 6 = 60
10 X 7 = 70
10 X 8 = 80
10 X 9 = 90
10 X 10 = 100
