Tic-Tac-Toe

Description

Rules of the Game

The game is to be played between two people (in this program between HUMAN and COMPUTER).
One of the player chooses ‘O’ and the other ‘X’ to mark their respective cells.
The game starts with one of the players and the game ends when one of the players has one whole row/ column/ diagonal filled with his/her respective character (‘O’ or ‘X’).
If no one wins, then the game is said to be draw.

Winning Strategy – An Interesting Fact
If both the players play optimally then it is destined that you will never lose (“although the match can still be drawn”). It doesn’t matter whether you play first or second.In another ways – “ Two expert players will always draw ”.
Isn’t this interesting ?
