Hello, Codeforces!
On Dec/19/2023 17:35 (Moscow time) the Codeforces Round 916 (Div. 3) will start. You will be offered 6-8 problems with expected difficulties to compose an interesting competition for participants with ratings up to 1600. However, all of you who wish to take part and have a rating of 1600 or higher, can register for the round unofficially.
The round will be hosted by rules of educational rounds (extended 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.
You will be given 2 hours and 15 minutes to solve 6-8 problems. 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 five 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 invented and prepared by Adilbek adedalic Dalabaev, Ivan BledDest Androsov, Maksim Neon Mescheryakov, Roman Roms Glazov, Alexander fcspartakm Frolov, and me. Also, big thanks to Vladislav Vladosiya Vlasov for his excellent coordination.
And, the last but not the least, thanks to Mike MikeMirzayanov Mirzayanov for Codeforces and Polygon systems!
Good luck in the contest! I hope you'll enjoy solving the problems we have prepared.
UPD: For technical reasons, rating for Codeforces Educational Round 160 will be recalculated after the Div. 3 round.
