Hi, Codeforces!

I'm glad to invite you to take part in Codeforces Round #721 (Div. 2), which will take place on 20.05.2021 17:35 (Московское время). The round will be rated for the participants with a rating lower than 2100. Participants from the first division are also welcomed to take part in the competition but it will be unrated for them.

You will be given 2 hours to solve 5-6 problems. Problems were created by members of Club of Programmers IIT (BHU)- rivalq, sharabhagrawal25, loud_mouth, DenOMINATOR, Bignubie, mallick630, shikhar7s, CoderAnshu and Me.

Monogon, ajit, kassutta, namanbansal013, Qualified, 4qqqq, Ekler, Rajdeep, wxhtzdy and kalki411 for testing and providing invaluable feedback.
