Ten Days of Code: Task 3

Problem Statement

CLI Tic Tac Toe
CLI based Tic Tac Toe with 2 players.

My Approach

Since, there are only two users, and no centralised server, the game logic will reside in each file. So I created a TicTacToe class. The class has the following methods:

p1Move() Ask Player 1's move and will keep asking untill it gets a valid input
p2Move() Ask Player 2's move and will keep asking untill it gets a valid input
find_winner() Will find the winner at the current state of the game and return the value
display_board() Display's the board neatly
isGameOver() will decide if the game is over

Now, let's discuss how I have decided the logic of the game. I am storing the board in a linear array of 9 elements, initially they have 0 else if p1 made a move it will be +1 else for p2 it will be -1. Now to check we will check if the rows, cols, diagonals and anti-diagonals have +3 or -3 if so then there is a winner else no winner.

One optimisation instead of going through the entire board every single time, I am looking at the corresponding rows, and cols, and diagonals of the last move, because only that will decide the game.

For the client and server script its simple socket programming.
