Hi!

Codeforces round #628 (vintage Codeforces round #2) will take place on Mar/14/2020 17:35 (Moscow time). It's rated for the second division, but, as usual, first division participants can take part out of competition.

The problems were created by me. I'd like to thank, and orz, antontrygubO_o for coordinating the round; ramchandra, pajenegod, aryanc403, taran_1407, Kuroni, mcdx9524, dorijanlendvaj, Andreasyan, 300iq, zoooma13, Osama_Alkhodairy, Mohammad_Yasser, and TripleM5da (special shout-out) for testing the round; and of course MikeMirzayanov for the great codeforces and polygon platforms.

You'll be given 6 problems and 2 hours to solve them.

UPD: the scoring distribution will be 500-750-1250-1750-2500-2750.

UPD: the editorial is out.

Good luck & Have fun!
