Tic-Tac-Toe Game with an unbeatable AI using Minimax Algorithm

Tic Tac Toe is a simple two-player game that is played on a 3x3 grid. The two players take turns marking their symbol (usually an "X" or an "O") on one of the empty squares on the board. The goal of the game is to get three of your symbols in a row, either horizontally, vertically, or diagonally. If a player succeeds in doing they win the game.
