I stumbled upon an intriguing variation of Tic Tac Toe shared by Twitter user lobotosasha (link: https://twitter.com/lobotosasha/status/1779156359449072032). In this modified version, players face an additional challenge: they cannot mark more than three cells with their shape. If they mark a fourth cell, their first marked cell disappears.

So, is it possible for anyone to win this game if both players play optimally?

Assuming that you cannot mark the cell where your shape will disappear after your move, do you think victory is possible, or are we stuck in an eternal stalemate?

Let me know what you think!

As a competitive programmer, you're probably looking for a way to showcase your skills and achievements to potential recruiters and fellow programmers. One effective method is to include your Codeforces profile stats in your github README.

This is where the Codeforces Readme Stats come in. This project, which I created, is a great tool that automatically generates beautiful statistics of your Codeforces profile, which can be added to your README to create a stunning profile that highlights your skills and achievements.

This has happened to me twice, where 1 index hashing is getting TLE but 0 index hashing with same logic is getting Accepted. Not sure if it's python issue or hashing complexity.
