Hi, Codeforces!

I'm glad to invite you to take part in Codeforces Round #721 (Div. 2), which will take place on May/20/2021 17:35 (Moscow time). 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, mallick630, shikhar7s, CoderAnshu and Me.

Huge thanks to those who helped make this round possible:

Aleks5d and KAN for their excellent coordination and for providing priceless feedback during contest creation.
Monogon, ajit, kassutta, namanbansal013, Qualified, 4qqqq, Ekler, Rajdeep, wxhtzdy and kalki411 for testing and providing invaluable feedback.
MikeMirzayanov for Codeforces and Polygon platforms.

We tried our best to create interesting problems and simple-to-read statements and we hope you have fun! Happy coding :)

We will soon be updating about the scoring scheme for the round.
