Solution for this Kata, but turned into a little game.
If we were to set up a Tic-Tac-Toe game, we would want to know whether the board's current state is solved, wouldn't we? Our goal is to create a function that will check that for us!
Assume that the board comes in the form of a 3x3 array, where the value is 0 if a spot is empty, 1 if it is an "X", or 2 if it is an "O", like so:
[[0, 0, 1],
[0, 1, 2],
[2, 1, 0]]We want our function to return:
-1if the board is not yet finished AND no one has won yet (there are empty spots)1if "X" won,2if "O" won,0if it's a cat's game (i.e. a draw).You may assume that the board passed in is valid in the context of a game of Tic-Tac-Toe.
