Hello Codeforces!

I am glad to invite you to my first official round Codeforces Round 630 (Div. 2), which will take place on Mar/31/2020 16:35 (Moscow time) (please note for the unusual starting time) and will be rated for all Division 2 participants.

You will be given 7 tasks and 150 minutes to solve them.

All tasks in this round were prepared by me. Hope that you will enjoy those tasks!

I would like to thank:

To avoid queueforces, we will provide small amount but strong (hope so) pretests for first few tasks. Hope it works!

Score distribution will be announced later.

Good luck and have fun!

UPD1: Score distribution: 500-1000-1250-1250-1750-2250-3000

UPD2: Contest is over, and here is the editorial.
