Tic-Tac-Toe

Create a two-player tic-tac-toe game in Ruby.

Requirements

• Must define at least two classes
• Must define at least one exception class
• Must use at least one Array
• Must use at least one Hash
• Must announce the winner when one player wins (three Xs or Os in a row, up, down, or diagonal)
• Must announce that the game ends in a tie if there are no available moves

Suggestions

Draw a game board using pipes (|) and dashes (-) that looks like this:

 1 | 2 | 3 
-----------
 4 | 5 | 6 
-----------
 7 | 8 | 9

Then prompt the player to use enter a number.

For example, if the first player enters 5, replace the 5 with an X. If the second player enters 9, replace the 9 with an O. If those are the first two moves, the board should look like this:

 1 | 2 | 3 
-----------
 4 | X | 6 
-----------
 7 | 8 | O

Bonus

If you finish early, try creating a one-player tic-tac-toe game that you can play against the computer. Try to make your artificial intelligence unbeatable.
