For this problem you need to use Mutual Recursion. This means one function will call another...

thanks for the question, here is the simple code in python.

====================================================================================

def steve(n):
    if n<=2:
        print('Steve wins the game')
        return
    if n%4==0:
        kate(n-3)
    else:
        kate(n-1)

def kate(n):
    if n<=2:
        print('Kate wins the game')
        return
    if n%2==0:
        steve(n-2)
    else:
        steve(n-1)

steve(1)
steve(5)
kate(1)
kate(2)

thanks !
