Hi, Codeforces!

Vladithur and I are pleased to invite you to our Codeforces Round #769 (Div. 2), which will be held on Jan/30/2022 17:35 (Moscow time). This round will be rated for participants with rating lower than 2100.

We would like to express our great gratitude to:

You will have 2 hours to solve 5 problems, one of which is divided into two subtasks.

The scoring distribution is 500 — 1000 — 1500 — 2000 — (1500 — 1500)
