Hi everyone!

I would like to invite you to my second Codeforces round, which I have created with my friends Ashishgup and Vivek1998299.

With that said, I bring to your attention our new Codeforces Round 548 (Div. 2) that will take place on Mar/21/2019 18:35 (Moscow time). If your rating is less than 2100, this round will be rated for you; otherwise, you can participate out of competition.

I would like to thank Ashishgup and Vivek1998299 for their help with preparing problems, vintage_Vlad_Makeev, mohammedehab2002 and Um_nik for testing the problems and cdkrot for coordinating our round. I would also like to thank MikeMirzayanov for the awesome Codeforces and Polygon platforms.

You will be given 6 problems and 2 hours to solve them. Scoring distribution will be announced later.

Good luck! :D

UPD1: Shortly after the contest, we'll be on the community Discord server to discuss the tasks.

UPD2: Score distribution is — 500-1000-1750-2250-2500-3000
