In order to introduce the system to the EJOI participants, we have uploaded previous EJOI problems to our system. All the links are available below.
For 2017, 2020, and 2021, the participants can read the problems in their native language (if the problems were translated to that language that year).
According to the EJOI rules, only C++ is supported.
The first two links are for the virtual contests. Participants can start the contest, and the timer for 4 hours will start. They will be able to submit their solutions only during that time. This is something similar to USACO style. In the third contest, you can upsolve problems as long as you want.
