(He last walked the Earth in round 538 btw.)

Hello Codeforces!

We are here to invite you to Codeforces Round #554 (Div. 2), which will take place at 24.04.2019 17:35 (Московское время).

The round will be rated for all Division 2 participants (with rating less than 2100), yet any Division 1 participants are welcome to join us out of competition.

The round will be cat themed. Raise your paws and prepare your catnips!

(Or even cat memes, while you're at it).

You will be given 6+1 problems ( 6 problems, one of them has 2 subtasks ) to solve in 2 hours. The round's problems were prepared by Xuan-Quang xuanquang1999 D. Nguyen, Duy-Bach Akikaze Le, Stefan stefdasca Dascalescu, Quang-Minh MofK D. Nguyen and our dear Codeforces coordinator Dmitry _kun_ Sayutin.

Gladly (or sadly), no interactive problem tonight!

Also, the tribute should be given to everyone within the team — we all make it possible:

  • Andrew GreenGrape Rayskiy for various problem suggestions and the infamous OMEGALULRIP influence. ;)
  • Xuan-Tung neko_nyaa Nguyen for testing the rounds and various suggestions in the core theme idea. Nya~.

Last but not least, I want to give a huge appreciation to MikeMirzayanov for the awesome Codeforces and Polygon platform, which makes this contest possible.

P/s: I will be at the Discord CP Community to discuss the problems after the coding phase. However, please follow the rules and don't discuss the problems during the contest by any means.

Wish everyone good luck and high rating!

P/s(2): Commies united!

P/s(3): A dear thank-you to Grigory gritukan Reznikov for the last-minute complete testing as well! ;)

UPD1a: Another comrade, Quang-Minh MofK D. Nguyen joined the fun! Kudos for the problem suggestion! ;)

UPD2: Score distribution: 500-1000-1500-2000-2000-(2250+750).
