The second round of the IOIT (International Olympiads in Informatics in Teams) is starting tomorrow, November 27th 2017! In the meanwhile, you can enjoy our teaser below and try to guess the next seven problems from the hints :)

If you missed the first, you can still join in; check this post for further details. The mirror contest will be 3 hours USACO-style, starting from 15:00 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!
