Hello, Codeforces!

I'm glad to invite you to Round 643 which will start at 16.05.2020 14:35 (Московское время). Please notice the unusual time.

There will be 6 problems in round, one of them will be interactive. If you are not familiar with interactive problems, you can learn about them here.

Round is based on Team Olympiad in Lipetsk which is being held for the fifth time. Problems were prepared by fake123, iura, Masha237, Villen3tenmerth, Inessa Shujkova (Lipetsk teams' coach) and me. I would like to thank antontrygubO_o for CF round coordination and testers: KAN, I_love_Tanya_Romanova, vepifanov, Merkurev, golikovnik, Ekler and some other people who asked me not to write about them :)

Of course, I'd like to thank all Codeforces team for this beautiful platform!
