TREMBLE BEFORE THE MIGHTY OMEGALULGRAPE

Hello Codeforces!

We are honored to invite you to Codeforces Round #538 (Div. 2), which will take place at 10.02.2019 17:05 (Московское время). The round will be rated for all Division 2 participants (with rating less than 2100). Still, we warmly welcome Division 1 participants to join us out of competition.

You will be given 6 problems to solve in 2 hours. The round's problems were initially prepared by Duy-Bach Akikaze Le, Xuan-Tung neko_nyaa Nguyen and Xuan-Quang xuanquang1999 D. Nguyen.

There will be an interactive problem in this round. Learn more about interactive problems here.

This is our first attempt in making a Codeforces round, so suggestions are much welcome to help us improve ourselves. ;)

We also want to thanks many friends for making this round possible:

  • Dmitry _kun_ Sayutin for coordinating the round, providing a neat idea on one problem and some Russian translations.
  • Andrew GreenGrape Rayskiy for various suggestions on the problems, some other Russian translations, and most importantly, peacefully submitted himself to be quarantined from pretests. ;)
  • Michal majk Svagerka for testing the round.
  • And last but not least, Mike MikeMirzayanov Mirzayanov for the amazing Codeforces and Polygon platform, without which this round would never be possible :D

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!

UPD1: Score distribution: 500-1250-1500-2000-2000-2750

UPD2: Editorial is published.

UPD3: The contest is finished. I apologized for the "somewhat" weak pretests at here and there. Anyway, time to celebrate our winners ;)
