The first round of the IIOT (International Informatics Olympiads in Teams) is starting tomorrow, November 15th 2021! In the meanwhile, you can enjoy our teaser below and try to guess the next nine problems from the hints :)
The open contest will be 3 hours USACO-style, starting from 17:30 in the CEST/CET time zone, and ending 27 hours after that (check this post for further details).
We hope that you will join us or encourage your students to do so!
