Hello, Codeforces!
On Mar/11/2024 17:35 (Moscow time) Codeforces Round 933 (Div. 3) will start.
You will be offered 7 problems, dedicated to the adventures of a restless mathematician, a programmer and just a funny character named Rudolf and his brother Bernard, and 2 hours 15 minutes to solve them. Problems have 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, solutions will be judged on preliminary tests during the round, and after the round, it will be a 12-hour phase of open hacks.
Note that the penalty for the wrong submission in this round is 10 minutes.
Remember that only the trusted participants of the third division will be included in the official standings table. 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)
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.
Problems have been created and written by: vladmart, Sasha0738, t0rtik, Alexey_Parsh, Mordvin13, daha.002, Vladosiya and natalina.
We would like to thank:
MikeMirzayanov for Polygon and Codeforces platforms and helping prepare the problems.
step_by_step, ashmelev for red testing.
KseniaShk, senjougaharin for yellow testing.
dan_dolmatov, SashaT9, FBI, SpicyOctopus for blue testing.
Gargera0, Matrosk1n, Alex_TULGU, Alenochka, gas for cyan testing.
Good luck!
UPD: Because of the technical issue (see the post https://mirror.codeforces.com/blog/entry/126654), temporarily the only available C++ compilers are: C++14 (GCC 6-32) and C++17 (GCC 7-32).
