Three years later, first ideas of a contest turned into this complete set of problems, so I am glad to invite you to take part in Codeforces Round #824 (Div. 2), which will take place on Oct/02/2022 17:35 (Moscow time). The round will be rated for the participants with rating lower than 2100. Participants from the first division are also welcomed to take part out of competition.
You will be given 2 hours 15 minutes to solve 6 problems. All the problems were created and prepared by me.
I would also like to thank:
- KAN for awesome coordination!
- Aleks5d, arzhantsev64, ChthollyNotaSeniorious, DanWallgun, flowerletter, Gegege337, Imakf, LeoRiether, mejiamejia, okwedook, PO3OBAR_Bblnb, SSerxhs, TomiokapEace, triple__a, wabadabakalakaboo for testing the round and giving significant feedback.
- mejiamejia for his help with extra testing.
- MikeMirzayanov, geranazavr555, unreal.eugene, DK318, and KAN for maintaining Codeforces and Polygon platforms!
Note that some problems have similar scores. Your sense of the scoring distribution may differ, don't forget to read further problems if you get stuck.
I look forward to seeing you on the leaderboard. I hope you'll enjoy all 6 problems and wish you good luck!
There is Codeforces Official Channel in Telegram with round announcements. For some reason, all posts get an overwhelming amount of thumbs down. Can we turn the situation around and let hearts win?
