Question

Design a recursive function that accepts an integer argument, n, and prints every second number from n down to a minimum of 0. Assume that n is always a positive integer.

Answer 1

def recursiveFunction(x):
    c=1
    if(x==0):
        print(x)
    else:
        recursiveFunction(x-1)
        if(x%2==0):
            print(x)

recursiveFunction(30)

Output:
