Hello Codeforces!

We are here to invite you to Codeforces Round #554 (Div. 2), which will take place at Wednesday, April 24, 2019 at 22:35UTC+8.

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!

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! ;)
