Hello Codeforces!↵
↵
We are here to invite you to Codeforces Round #554 (Div. 2), which will take place at [contest_time:1152].↵
↵
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 ~xuanquang1999,2019-04-23 D. Nguyen, Duy-Bach ~Akikaze,2019-04-23 Le, Stefan ~stefdasca,2019-04-23 Dascalescu, Quang-Minh ~MofK,2019-04-23 D. Nguyen and our dear Codeforces coordinator Dmitry ~_kun_,2019-04-23 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,2019-04-23 Rayskiy for various problem suggestions **and the infamous OMEGALULRIP influence.** ;)↵
- Xuan-Tung ~neko_nyaa,2019-04-23 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,2019-04-22 for the awesome Codeforces and Polygon platform, which makes this contest possible.↵
↵
P/s: I will be at the [Discord CP Community](https://mirror.codeforces.com/blog/entry/52778) 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.↵
