The final round of the IIOT (International Informatics Olympiads in Teams) is starting next Friday, February 21th 2020! In the meanwhile, you can enjoy our teaser below and try to guess the next eight problems from the hints :)
If you missed the first rounds, you can still join in; check this post for further details. The mirror contest will be 3 hours USACO-style, starting from 13:00 in the CEST/CET time zone, and ending 24 hours after that.
We hope that you will join us or encourage your students to do so!

I'm not in the scoreboard why?
