Croatian Open Competition in Informatics - COCI 2019/2020
Internet online contest series
As part of the COCI series, we are hosting an Internet online contest with problems from the Croatian Olympiad in Informatics 2020. The contest is primarily intended for high school contestants, but is open to all interested!
This contest was used in Croatia to select members of the IOI 2020 team. There will be four tasks and the contest will be five hours long. The contestants will also have full feedback with at most 50 submissions per task .
It will be held on Saturday, October 3, starting at 15:00 (GMT/UTC) .
Check out your local times at https://hsin.hr/coci/next_contest.html
You may use Python, Pascal, C, C++ or Java as your programming language of choice.
The contest will also be featured on a newly-developed judging system. If your students wish to get a bit more familiar with the system, we have uploaded the last 14 COCI seasons for them to practice on. Most problems (except for the very easy ones) have English translations. This judge will also be used for the next COCI season.
The two relevant websites are:

https://evaluator.hsin.hr/ - judging system
We hope that you will join us or encourage your students to do so!
This is the fourteenth year in a row that we are hosting the COCI series. You can find the tasks (statements, test data and solutions) from the previous years at https://hsin.hr/coci/. There are over 600 original tasks for students to practice on!
