，这个代码中程序运行忽略了对输赢的判断以及预测玩家下棋的输赢预测堵截，有大神可以指导一下问题点解决方法吗，不要太难基础的，谢谢

Welcome to the greatest intellectual challenge of all time: Tic-Tac-Toe.
This will be a showdown between your human brain and my silicon processor.
You will make your move known by entering a number,0 - 8. The number will
correspnd to the board position as illustrated:

0 | 1 | 2
---------
3 | 4 | 5
---------
6 | 7 | 8

Prepare yourself, human. The ultimate battle is about to begin. \n
