Lecture 54:- Let's Code Indirect Recursion

Certainly! Here's an example of indirect recursion in Python, where two functions call each other in a cyclical manner:

pythonCopy code

def functionA(n):    if n > 0:        print("Function A:", n)        functionB(n - 1)  # Call function B def functionB(n):    if n > 0:        print("Function B:", n)        functionA(n - 1)  # Call function A # Call function A to start the recursion functionA(5)

In this example, the functions functionA and functionB call each other indirectly. Each function prints its value and then calls the other function with a decremented value, forming a cyclical dependency between the two functions.

When executed, the program will output:

javascriptCopy code

Function A: 5 Function B: 4 Function A: 3 Function B: 2 Function A: 1

Note that the recursive calls terminate based on the condition n > 0. Without such conditions, the recursion would continue indefinitely, leading to infinite recursion.

Indirect recursion can be useful in various scenarios where multiple functions need to collaborate or solve a problem collectively. However, it's essential to ensure that appropriate termination conditions are in place to prevent infinite recursion.
