# Example:
# Write a function that counts down from N and then prints "Go!".
# Write both a recursive version and an iterative version.
# JMR 2018

# Recursive version
def countdownR(n):
    if n > 0:
        print(n)
        countdownR(n-1)
    else:
        print("Go!")

# Iterative version
def countdown(n):
    while n>0:
        print(n)
        n = n-1     
    print("Go!")

# MAIN PROGRAM
# Test both:
countdownR(5)
countdown(3)
