Codeforces Round #748 (Div. 3)

Revision en5, by MrPaul_TUser, 2021-10-15 20:42:19

Hello, Codeforces!

I'm glad to invite you to amazing (we've tried to make it such) Codeforces Round 748 (Div. 3) which will start on Oct/13/2021 17:35 (Moscow time). This round is made by me (MrPaul_TUser), a significant contribution to the round was also made by MikeMirzayanov and BledDest.

The round contains 6-8 problems. The difficulties of the problems are expected 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 1600 or higher, can register for the round 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 tried to make really strong tests — just like you will be surprised if many solutions fail after the contest is over.

You will be given 6-8 problems and 2 hours 15 minutes to solve them.

Note that the penalty for the wrong submission in this round (and the following Div. 3 rounds) is 10 minutes.

Remember 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 trusted participants of the third division, you must:

  • take part in at least two rated rounds (and solve at least one problem in each of them),
  • do 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.

Thanks to _c_k_r_, Vladosiya, Ahmed_Salama, BitHashTech, powergee101, ncduy0303, I_Remember_Olya_ashmelev, God_Of_Code, OlegZubkov, mahade31, arjunsanjeev7, and SmartCoder for testing the round and improving tasks.

Good luck and have fun!
