The game
idea of Sanbang is as follows:
**1,** first print the menu and tell the player how to start the game. If you enter 1, the game starts. If you enter 0, the game ends. .
**2, **Initialize the board so that the board is blank.
**3,** Print the chessboard.
**4,** Then use the while loop to continue the game, first the player plays chess, and then the computer plays chess, each time you play chess, you must print the chessboard and judge whether you win or lose.
**5,** Until someone wins or the board is full, the game is over.
