TicTacToe-Game

• Basic Simulation of a Tic Tac Toe Game in Python
• Motivated by the 2nd screening coding round at HashedIn ....which I couldn't clear at that time (HashedIn On-Campus Placement Coding Round 2019)

Libraries used :

• OS
• Math
• NumPy

Variables Used in our Project :

• arr = Array to keep track of Player's move
• pos = Array to give Player information on the positions
• now = keeps track of which Player turn it is now i.e 1 or 2
• won = keeps track if Player1 or Player2 won i.e won = 0 -> No one won won = 1 -> Player 1 won won = 2 -> Player 2 won
• first = tells us if it's the beginning of the game or not i.e. first = 0 -> Beginning of the Game first = 1 -> Not the Beginning of the Game

Functions to check if someone has completed a line :

• Horizontal Check Up -> check_horizontal() function checks for any complete horizontal line
• Vertical Check Up -> check_vertical() function checks for complete vertical line
• Diagonal Check Up -> check_diagonal() function checks for complete diagonal line

Algorithm :

1. Refresh 3 variables for every new game i.e won, arr, first.

2. Run the Game until someone win's it i.e run the while loop until won becomes 1 or 2

3. Depending on whether it's the beginning of the game or in between :

• If it's the beginning of the game i.e first = 0 -> Ask who's going first (Player 1 or Player 2)

• Else -> switch player's turn to ensure both player plays at alternate turns

4. Ask for the Player's move i.e row & column number -> Then mark the position with 'o' for Player1 or 'x' for Player2

5. Print the array after each move

6. Check for any complete horizontal, vertical or diagonal line

• If found => Return the Player's no. & announce the winner --> End the loop
• Else => Continue Playing --> Continue the loop

7. Mark first = 0 -> After the First move
