[bug]:Backend Implementation for Tic-Tac-Toe Game

[aman031298]

Description: We need to implement the backend logic for a Tic-Tac-Toe game. This will include APIs to manage game state, player moves, and game outcomes. The backend should handle the following features:

Create a new game
Join an existing game
Make a move
Check game status
Determine the winner or if the game is a draw
Requirements:

Game State Management:

Maintain the state of the game board.
Track player turns.
Reset the game when a new game is started.
API Endpoints:

POST /game: Create a new game and return a unique game ID.
POST /game/{gameId}/join: Join an existing game.
POST /game/{gameId}/move: Make a move in the game.
Request body should include player ID, position (row, column).
GET /game/{gameId}/status: Retrieve the current status of the game.
Validation:

Ensure moves are valid (e.g., positions within bounds, position not already taken, correct player's turn).
Check for game-winning conditions or if the game is a draw after each move.
Error Handling:

Return appropriate error messages for invalid actions.
Handle edge cases such as invalid game ID, joining a full game, etc.
Technologies:

Use a framework like Express.js (Node.js) or Flask (Python).
Use a simple in-memory store for game state (e.g., a dictionary or an in-memory database like Redis).
Tasks:

Set up the project structure and dependencies.
Implement the game state management logic.
Develop the API endpoints.
Add input validation and error handling.
Write unit tests for the game logic.
Write integration tests for the API endpoints.
Additional Notes:

Consider scalability and performance for future enhancements (e.g., using a database for persistent storage).
Ensure the code is well-documented and follows best practices for readability and maintainability.
