By _O_v_O_, history, 3 hours ago, In English

你好，Codeforces!

We are excited to invite you to participate in Codeforces Round (Div. 2), which will be held on Oct/24/2026 14:05 (Moscow time). Note the unusual start time of the round.

You will be given 2 hours to solve 6 problems. One of the problems will be divided into 2 subtasks. At least one problem will be interactive so we recommend reading the guide to interactive problems if you have not encountered them before. All the problems were authored and prepared by Getaway_Car and me, _O_v_O_.

We'd like to express our sincere gratitude to:

Good Luck & Have Fun! We hope you enjoy this round!

The scoring distribution will be announced later.
