Question

I am writing a program that must find if a number is even or not. It needs to follow this template. I can get it to find if a number is even or not recursively

Answer 1

This template will help. You need to fill in the commented lines. The one you have in the question won’t work – you aren’t passing anything into isEven. This will only work if n >= 0, otherwise it will crash your program. Easy enough to fix if you ever need to deal with negative numbers.

def isEven(n):
    if n == 0:
        # Number is even
    elif n == 1:
        # Number is odd
    else:
        # Call the function again, but with a different n
