My code of problem H that passed the pretest got TLE on test 1. Is there something wrong with the judge? Why it can pass the sample within the contest but failed in system test. There is no randomization in my code.

I think you should ping some admin for rejudge.

Hi, I tested your code submission locally with the test sample of the first testcase, and it appears it takes 12 seconds to output the result. So I don't really think it is a problem from codeforces's judges. Anyways, good job man for this incredible result !

    That Makes me wonder , since the rejudge happened after the rating calculation , will the updated rating for StarSilk apply in the next rollback 💀

    (moved from Rank $$$7$$$ to Rank $$$6$$$)

      I assume so, although I’m not involved with rollbacks.

There should be some clarification of some general threshold where x% of the same submission has to be accepted before rejudging. I think there is some balance between “something wrong/slow with systems” vs “solution works most of the time” (which if FST should be final).
