Codeforces Round 1080 (Div. 3)
by chromate00 · CodeforcesOh hello there. I, chromate00, am back! Oh no, I hope you are not misunderstanding me, I'm not pulling a joke on the announcement this time. I'm too busy for that right now. So here's the (mostly copy-pasted) announcement of Codeforces Round 1080 (Div. 3).
Anyways. Starting from Feb/15/2026 17:45 (Moscow time), you will be given $$$\mathbf{7}$$$ or $$$\mathbf{8}$$$ problems to be solved in $$$\mathbf{2.5}$$$ hours.
The round will be hosted by 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. Also, note that there is no score distribution but the usual penalty of 10 minutes for each wrong submission, following the rules of educational rounds.
Remind yourself that only the trusted participants of the third division will be included in the official standings table. As it is written by link, this is a compulsory measure for combating unsporting behavior. To qualify as a trusted participant of the third division, you must:
- take part in at least five rated rounds (and solve at least one problem in each of them)
- not have 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).
Also, note the rule restricting the use of AI. If you are caught while breaking this rule, you will be sent to cry's new basement on Mars without oxygen.
This round is made possible by the help of the following people:
- Vladosiya for coordinating the round (and translating the statements);
- Proof_by_QED for his continued support;
- Dominater069 for red-black testing;
- awoo, __baozii__, catgirl, ttamx, sammyuri, Intellegent for red testing;
- Arpa, omsincoconut, spike1236, beaaaan, -firefly-, temporary1, turska, Friedrich for yellow testing,
- SpyrosAliv, reirugan, tin.le2, yse; YamOCHca, conjectureguy, Edeeva for purple testing;
- ananthak, Ermiooo159, my_bloody_valentine, ai4youej, itz_pabloo, bestial-42-centroids for blue testing;

I hope that you will enjoy the contest. Good luck and have fun!
