Problem Statement

Three players each guess a positive integer greater than 0, and then share them simultaneously. The winner is chosen following this formula:

• If any two players have chosen the same number, the game is a tie.
• If all players have chosen even numbers, or all players have chosen odd numbers, then the smallest number wins.
• Otherwise, the largest number wins.

def main():
    p1 = int(input("Enter a positive integer for player 1: "))
    p2 = int(input("Enter a positive integer for player 2: "))
    p3 = int(input("Enter a positive integer for player 3: "))

    # debugging statements
    print("player 1 chose {}".format(p1))
    print("player 2 chose {}".format(p2))
    print("player 3 chose {}".format(p3))


main()

Conditions to Check

• Are the numbers all even?
  • If so, which number is smallest?
• Are the numbers all odd?
  • If so, which number is smallest?
• Are the numbers not all even or odd
  • If so, which number is the largest?
• Are all numbers greater than 0?
