CROATIAN OPEN COMPETITION IN INFORMATICS
 
Internet online contest series
 
Over the next six months we will organize seven online contests as a warm-up for the 2020 season of high school programming competitions. Everyone is welcome to participate!
 
Each contest will be three hours long and will feature five tasks. 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.
 
The first contest will be held on Saturday, 19 October 2019, starting at 14:00 (GMT/UTC). You may use Python, Pascal, C/C++ or Java as your programming language of choice.
 
Instructions, problems and the contest system will be located at

This web page will be available for registration 48 hours before the contest.
