Question

1. 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

import time

def printNumberDown(n):
    if n!=-1:
        print(n)
        time.sleep(1)
        printNumberDown(n-1)
    
def main():
    n=int(input("Enter n: "))
    printNumberDown(n)


main()
