Technique to switch players
I have assigned the value 0 to the first player and the value 1 to the second player, regardless of who plays first. If the human chooses to play first, the value 0 is assigned to the human variable, and the value 1 is assigned to the computer variable, and vice versa. Throughout the project, the system checks the current player against the human or computer variable to determine the player type. The first player always uses "X," while the second player uses "O." However, the value assigned to a box depends on the player type: the value of a box chosen by the human is 3, and the value of a box chosen by the computer is 5.
