I participated in Codeforces Round #713 (Div. 3)

I had solved the Problem 1512G — Short Task, during the contest, which I believe at least ran on 3 pretests, as many participants got WA on TC 3, during the contest.

My During-Contest AC Code ran in 1940ms, with "Pretests Passed" Verdict.

The intended complexity for the problem, was O(10^7 log(10^7)), as described in the editorial.

My solution's complexity was the same.

After system test, my during-contest solution got TLE'ed on TC 3, the case which was included in pretests as well. (Code)

After system test, I submitted the same solution, without changing a single word/line, it got AC'ed in 1965 ms. (Code).

I saw the leaderboard and seems like I am not the only one to have a TLE'ed solution.

I truly agree that ~100ms non-deterministic difference in run-time is possible. But, if the intended solution requires TL so close to 2 sec., then it would have been better to put the TL as 2.5s or 3s. Also, this would have helped Python/Java solutions, which TLE'ed, to pass, and also the non-deterministic difference in run-time wouldn't have affected the solutions, with "intended" complexity.

Please, look upon this suggestion MikeMirzyanov.

Thank you. Correct me, if I have wrote something wrong or contradictory.
