Question

 Write a tic-tac-toe game to be played between two players. Use an array to emulate 
the game board. The array can be one dimensional or two-dimensional. Initialize 
each element of the array to "_" (underscore). YOur program should start by 
displaying the initial board and then let player X and player O take turns. 
Associate X with player X's moves and O with O's. Determine as the game 
progresses whether there is a winner or the game tied. If one of the player wins the
game identify it as player X  or O. All Xs or Os in a row, in a column or in a diagonal
is a winning condition. When no more element is left the game is a tie.


Expected Output:
(i) X wins.
