We are glad and excited to invite you to take part in [contest:2193], which will take place on [contest_time:2193]. You will be given **2** hours and **15** minutes to solve **7-8** probmles. At least one problem will be interactive, so we highly recommend to read [guide for interactive problems](https://mirror.codeforces.com/blog/entry/45307) before the contest.↵
↵
The round will be hosted by the rules of educational rounds (extended ICPC). Thus, all solutions will be judged on preliminary tests during the round, and after the round, there will be a 12-hour phase of open hacks. After the open hack phase, all accepted solutions will be rejudged on successful hacks.↵
↵
[As a reminder](https://mirror.codeforces.com/blog/entry/59228), only trusted participants of the third division will be included in the official standings table. This is a compulsory measure for combating unsporting behavior. To qualify as a trusted participant of the third division, you must:↵
↵
- take part in (and solve at least one problem in) at least five rated rounds↵
- and not have had a rating of **1900** or higher at any moment in time.↵
↵
Regardless of whether you are a trusted participant of the third division or not, if your rating is less than **1600**, then the round will be rated for you (unless you register unrated).↵
↵
Problems were authored by [user:KluydQ,2026-01-23], [user:YF_YUSUF,2026-01-23], [user:Wansur,2026-01-23], [user:Mendeke,2026-01-23].↵
