Hello, Codeforces!

On Dec/22/2024 17:35 (Moscow time) the Codeforces Round 995 (Div. 3) will start. The round will contain 7 problems, which are mostly suited for participants with rating below 1600 (or we hope so). Although, as usual, participants with rating of 1600 and greater can register for the round unofficially. Participants with rating below 1600 can also use unrated registration to participate unofficially.

The round will be hosted by rules of educational rounds (extended ACM-ICPC). Thus, during the round, solutions will be judged on preliminary tests, and after the round it will be a 12-hour phase of open hacks (we hope that our tests are strong enough, so there won't be too many solutions hacked during this phase).

You will have to solve 7 problems in 2 hours and 15 minutes. The penalty for a wrong submission is equal to 10 minutes.

We remind you that only the trusted participants of the third division will be included in the official standings table. As it is written on the blog which you can access by this 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 two rated rounds (and solve at least one problem in each of them),
• not have a point of 1900 or higher in the rating.

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.

The problems were prepared by Neon, fcspartakm, awoo, adedalic and me. We hope you enjoy solving them!

We would also like to thank MikeMirzayanov for his Codeforces and Polygon platforms, and Vladosiya for coordinating the round.

The contest was tested by shnirelman, k1sara, leovl48, jai_hanuman_orz, saba_goduadze, SashaT9 and RohitLakra. Thank you for helping us in evaluating the difficulty better and in getting rid of ambiguity in statements!

Good luck, and see you during the contest!
