Exactly 300 Codeforces rounds passed since my first one (Round 304). I have learned a lot of things here and have much fun in participating in the competitions. Now, I want to contribute to this community by proposing some problems. I hope that you will find something interesting in solving them.
- MikeMirzayanov for the powerful Polygon and Codeforces system.
- isaf27 for coordinating the round.
- Um_nik, arsijo, opukittpceno_hhr, kocko, Feynman for testing the round.
There will be roughly 6 problems in each division. Scoring will be announced later.
