Declare and implement a function called
gameOver receives a single 3x3
Array<CharArray> as a parameter, representing a tic-tac-toe board,
with each cell containing either a
O, or a
gameOver should return
X has won the game,
O has won the game, and a blank space (' ') otherwise,
including in the case of ties.
(Ties should probably be handled differently, but you can use a ' ' for now.)
Do not check the diagonals!
