Codeforces round #649 will take place on 13.06.2020 18:05 (Московское время). 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 my forever orzable coordinator antontrygubO_o; my incredible army of testers dorijanlendvaj, 300iq, Osama_Alkhodairy, AmShZ, Taran_1407, TigranMec, _Aaryan_, Mohammad_Yasser, zoooma13, lavish315, Utkarsh.25dec, NOOBxCODER, and Laggy; and, of course, you-know-who for the amazing codeforces and polygon platforms.
This time, in an effort to kill type-races and because I'm lazy, you'll be given 5 problems and 2 hours to solve them.
UPD: the scoring distribution will be 750-1000-1500-2000-2500.
UPD: the editorial is out.
UPD: congratulations to the winners!
Good luck & Have fun :D
