Hello Codeforces!

I am glad to invite you to Codeforces Round 630 (Div. 2), which will take place on 31.03.2020 16:35 (Московское время) and will be rated for all Division 2 participants.

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

I would like to thank: - awoo for great coordination of this round, and the idea of solution of one task! - Nanako, Nezzar for useful discussion and testing of those tasks! - antontrygubO_o, McDic, vovuh, TBeumsJryi, socho, Oak_limy, Stresshoover, I1I1I11I1I1, defolaut, hx073269 and Pavlova for testing those rounds and invaluable suggestions! - MikeMirzayanov for great systems Codeforces and Polygon!

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

Good luck and have fun!
