Hello Codeforces!

Once again, we are glad to invite you all to Codeforces Round 753 (Div. 3), the third division round held on 02.11.2021 17:35 (Московское время). This round was prepared (again) by me and MikeMirzayanov. The problems are different but our anticipation is the same :) Hope you will like the problems we've prepared!

Big thanks to MikeMirzayanov for great ideas as well as for helping me with writing good statements and better tests. I'm still a bit slow with some aspects of preparing problems so it's a really noticeable help for me.

Also special thanks to <a list of testers that will be participating in this round's testing>. And last but not least, thanks to everyone who'll be participating! This round contains 7 problems and is expected to have a decent level of difficulty 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 tests strong enough but it doesn't at all guarantee that open hacks phase will be pointless.

You will be given 7 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.

Good luck to everyone!
