Codeforces Round #630 (Div. 2)

Revision en9, by triple__a, 2020-03-29 09:26:39

Hello Codeforces!

I am glad to invite you to 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.

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 will provide small amount but strong ~~(hope so)~~ pretests for first tasks. Hope it works!

The number of tasks and tasks and point distribution will be announced later.

Good luck and have fun!
