- [user:MikeMirzayanov,2020-09-04] for the Codeforces and Polygon platforms.↵
↵
There will be **5 problems** in each division and will be given **2 hours** to solve them (or post memes in the comments if you can't solve any).↵
↵
We tried to make interesting problems, short statements, useful samples and strong pretests, and we hope you will like it.↵
↵
Scoring will be announced shortly **before** the round and editorial will be posted shortly **after** the round (it is already written).↵
↵
Good luck!↵
↵
**UPD:** The number of problems is now 5 in each division.↵
↵
**UPD2:** Score distribution:↵
↵
- Div.1: **500 — 1000 — 1500 — 2250 — 3000**↵
- Div.2 : **500 — 1000 — 1750 — 2250 — 3000**↵
↵
**UPD3:** [Editorial](https://codeforces.net/blog/entry/82366) is out↵
