Assignment : Game of Nim
Game of Nim
Nim is a game of strategy in which two players take turns removing sticks from a common pile. There are many variations of Nim but we will stick with a simple version. On each turn a player must remove either 1 or 2 sticks from the pile. The goal of the game is to be the player who removes the last stick.
You will design a game in which one human player is competing against a computer. To simplify your work the person will always take the first turn.
While there is a winning strategy for this game, you are only required only to create a computer player that makes random, but valid, moves.
Round 0: 7 at start human takes 2, so 5 remain Round 1: 5 at start computer takes 2, so 3 remain Round 2: 3 at start human takes 2, so 1 remain Round 3: 1 at start computer takes 1, so 0 remain The computer wins / you lose!
- Begin by prompting the user for the initial number of sticks. In the example above, it appears that 7 sticks were used in the game.
- The human (as always in this assignment) made the first move.
- Clearly, the human could have played better in the above game.
- The computer randomly removes 1 or 2 sticks, but cannot remove more sticks than are left.
- The human is prompted at each turn for how many sticks he or she wants to remove.
Be careful! A human might enter 5 if 5 sticks are left, and if you are not careful, the human could win by “playing” in that way. Don’t accept the user’s input if it is illegal. You may assume that they will only enter valid integers, but you should continue prompting until you get a valid value.
- Start your work by creating a
Nimclass in the
ArgsProcessorto prompt for inputs.
- Your program must continue play until somebody (computer or human) wins.
- Your output should resemble the sample output shown above. It should clearly show if the computer or the human wins.
- When it’s time to demo be prepared to discuss how you would implement a “smarter” strategy for the computer player.
