Coming soon IOI 2022 in Indonesia
Over the next six months we will organize seven online contests as a warm-up for the 2022 season of high school programming competitions. Everyone is welcome to participate!
Each contest will be three hours long and will feature five tasks. The contestants will also have full feedback with at most 50 submissions per task. The tasks will be of widely varying difficulty; we hope that many beginner or up-and-coming contestants will participate, as well as the more experienced ones.
Check out the local times of the next contest 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 15 COCI seasons for them to practice on. Most problems (except for the very easy ones) have English translations.

We hope that you will join us or encourage your students to do so!
