Codeforces round #716 will take place on Apr/19/2021 16:35 (Moscow time). It's rated for the second division, but, as usual, first division participants can take part out of competition.
The problems are based on the Egyptian IOI qualification, and they were created by me and mahmoudbadawy. I'd like to thank:
- KAN and Nebuchadnezzar for their excellent coordination.
- antontrygubO_o for improving a problem, then rejecting all our problems without reading them, then testing the round.
- Yousef_Salama, Mohammad_Yasser, Noureldin, and Commando_ for testing the official contest.
- 74TrAkToR and psevdoinsaf for testing the round.
- MikeMirzayanov for the great codeforces and polygon platforms.
This may be the most and only balanced round I've ever set. You'll be given 5 problems and 2:15 hours to solve them.
UPD: the scoring distribution will be 500-1000-1500-2000-2500.
UPD: the editorial is out.
UPD: congratulations to the winners:
Good luck & Have fun :D
