It's me again!
Codeforces round #717 will take place on Apr/21/2021 16:35 (Moscow time), an hour early than the usual timing. 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, and some of them are based on the Egyptian IOI qualification. I'd like to thank:
- KAN and Aleks5d for their excellent coordination.
- Akulyat, __cucumber__, Randle, Riladavin, Waley, MForest, _Stefan_, RabbitPower, and the official contestants, I guess, for testing the round.
- MikeMirzayanov for the great Codeforces and Polygon platforms.
You'll be given 5 problems, but this time you'll have 2 hours to solve them.
UPD: the scoring distribution will be 500-1000-1500-2000-2750.
UPD: the editorial.
UPD: congratulations to the winners:
Good luck & Have fun :D
