The first round of the IIOT (International Informatics Olympiads in Teams) is starting tomorrow, November 11th 2019! In the meanwhile, you can enjoy our teaser below and try to guess the next nine problems from the hints :)

Check this post for further details on how to join in. The mirror contest will be 3 hours USACO-style, starting from 15:00 in the CET time zone, and ending 24 hours after that.

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