Nim is a simple game where the second player - if they know the trick - will always win. The game has only 3 rules.
- start with 12 tokens
- each player takes 1, 2, or 3 tokens in turn
- the player who takes the last token wins.
To win every time, the second player simply takes 4 minus the number the first player took. So if the first player takes 1, the second takes 3 - if the first player takes 2, the second should take 2 - and if the first player takes 3, the second player will take 1.
- Task
Design a simple Nim game where the player goes first, and the computer always wins. The game should enforce the rules.
