Hi all,

Croatian Olympiad in Informatics (COI) represents the first major step towards forming the Croatian IOI team. As you know, we usually hold an online mirror of this contest as the last round of the COCI season.

On that note, I'm happy to invite you to join us on Sunday, April 25, starting at 14:00 (GMT/UTC). The contest will feature 3 to 5 IOI-style tasks and it will last for 5 hours. You will also have full feedback with at most 50 submissions per task.

You can access the judging system here. The registration period ends 1 hour before the beginning of the contest (look it up under "Events").

Hope you'll enjoy the contest.
