Hi, what is the expected difficulty and required prior knowledge? Do you think it is a good training for an ICPC regional contest, for example, ICPC SWERC?

Thanks!

Are three different computers allowed for each team member or only one is allowed for a team?

      Sorry for not knowing ICPC rules, but could you please tell me can the three different computers be used at the same time?

    Problems will not be sorted according to difficulty level. Three or Four problems will be easy to solve. Rest all of them will be hard(according to my level).

    The expected difficulty should be around ICPC regional level. You can check last year's mirror here.

Is a debriefing expected for the contest? I really liked the tasks, I would like to complete them.

Problem F is ridiculous. A straight brute force runs less than $$$2$$$ s, as fast as the standard solution.

    Sorry, we didn't expect for there to be a brute force solution that fast. Unfortunately, it's too late for us to change anything about that.
