Hello, Codeforces!

We are holding a mirror for the recent Romanian IIOT National Round.

IIOT (International Informatics Olympiads in Teams) is a team olympiad for teams of 4 highschool students organised in collaboration with Italy, Hungary and Syria.

Some details about the contest:

• The mirror is taking place on Kilonova. Here is the contest link.
• The mirror is USACO style, meaning that the mirror is open till 23:59PM March 12th (GMT+2 time), but you can choose any 3 hour window before then. You will have 6 problems of various difficulties. Based on the onsite results, we believe that some problems might be challenging even for some grandmasters.
• The statements are written in English.
• The supported languages are C, C++, Go and Python.
• The Romanian writers and contributors for this year's rounds are: bicsi, loan, apostoldaniel854, popabogdannnn, stefdasca, MVB, vladsuper5555, proflaurian and Vlad-Mihai Bogdan.

Good luck!
