Nim game

You are encouraged to solve this task according to the task description, using any language you may know.
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 human player goes first, and the computer always wins. The game should enforce the rules.




V tokens = 12
 
F getTokens(curTokens) -> N
   print(‘How many tokens would you like to take? ’, end' ‘’)
   V take = Int(input())
 
   I (take < 1 | take > 3)
      print("Number must be between 1 and 3.\n")
      getTokens(curTokens)
      R
 
   :tokens = curTokens - take
   print(‘You take #. tokens.’.format(take))
   print("#. tokens remaining.\n".format(:tokens))
 
F compTurn(curTokens)
   V take = curTokens % 4
   :tokens = curTokens - take
   print(‘Computer takes #. tokens.’.format(take))
   print("#. tokens remaining.\n".format(:tokens))
 
L tokens > 0
   getTokens(tokens)
   compTurn(tokens)
 
print(‘Computer wins!’)
