Hi all,
The Central European Olympiad in Informatics (CEOI) 2021 is starting tomorrow and we'd like to invite you to participate in two online mirror contests that will feature the same problems as the two competition days.
The day 1 mirror will take place on Thursday, September 2nd, 11:00 CEST, and day 2 mirror will take place on Saturday, September 4th, 11:00 CEST. Both contests will last for 5 hours, contain 3 IOI-style problems, and have full-feedback.
In order to participate in the CEOI 2021 Online Mirror contest, you'll need an account on evaluator.hsin.hr. After logging in, you can register for the Mirror contests on the "Events" page.
Hope you'll enjoy the contests.
