Codeforces Round #739 (Div. 3)

Правка en1, от MrPaul_TUser, 2021-08-17 10:41:05

Hello, Codeforces!

I'm glad to invite you to amazing (we've tried to make it such) Codeforces Round 739 (Div. 3) which will start on Aug/18/2021 17:35 (Moscow time). This round is my (MrPaul_TUser) second round a significant contribution to which was also made by MikeMirzayanov, BledDest, DK318, unreal.eugene, and geranazavr555.

The round contains 7 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. I tried to make strong tests — just like you will be upset if many solutions fail after the contest is over.

You will be given 7 problems and 2 hours 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 artsin666, ashmelev, powergee101, WitchOfTruth, ivanzuki, mahade31, _c_k_r_, iankury, God_Of_Code, Killever, and Ahmed_Salama for testing the round and improving tasks.

Good luck and have fun!
