My solution to Problem B of 913 Div3 got TLE in system testing https://codeforces.net/contest/1907/submission/235878287, however resubmitting the exact same solution now gets accepted https://codeforces.net/contest/1907/submission/236034573
Can the TLE submissions be re-evaluated? The TLE is likely due to server overload during the system testing. Additionally, Test case #5 might have been included in the original tests which my submission passed during the live contest itself. Vladosiya MikeMirzayanov pashka
Unfortunately it may happen that the same solution gets TLE or OK if it is very close to the time limit, like in your case (982 ms vs 1000 ms). We don't reevaluate such solutions after the contest is finished.
some functions have unfixed time complexity, so lucky is also an important factor. I've done some problems with 200 submittions , 199 TLE and 1 AC~~
