Hello Codeforces,

On behalf of the international scientific committee of IIOT, we would like to invite you all to the mirror of the international round of this year's IIOT, contest which took place in Egypt.

You are given 9 problems and 4 hours to solve the problems and it is recommended to solve the problems in teams of up to 4 members.

The contest is organized with USACO-like rules, as the mirror lasts until 7th of June, 23:59 UTC+3 and you can choose a window of 4 hours to solve the tasks together with your teammates. You are limited to 30 submissions per problem and the scoring style is the same as in OI (each problem has 100 points and there are subtasks for each problem as well).

The link of the mirror is here.

Thank you and we are looking forward to see you join the contest.
