Hello @admin , It is kinda necessary to rejudge the submissions (during contest) for the problem [BENCHP](https://www.codechef.com/problems/BENCHP), after updating the test cases for the problem. [This](https://discuss.codechef.com/t/benchp-editorial/88774/55) comment proves that the test cases are weak. There could be many submissions like [this](https://www.codechef.com/viewsolution/45720222) that could have passed during the contest. Rejudging them can bring changes to the leaderboard - as a result, rating changes can also be updated. This is a serious issue one should look into. > [@BENCHP - Editorial](https://discuss.codechef.com/t/benchp-editorial/88774/55): > > LOL, why is your code failing for this test case: Input 1 3 9 7 1 2 2 Your Output NO Expected Output YES So, can we conclude that the test cases are weak? @cubefreak777 what do you say about this (just an opinion)? @rhythmvarshney time complexity of your code is N\log{N} because you are sorting the Array. I am locking your code now. play_button Your so called O(N) code ---

After completion of contest, nothing can be done. Only some extra TC can be added for practice section ---

the code is incorrect … the testcases are fine ---

But that’s not fair. There could be many such submissions during the contest. Who knows - there could be major changes in the leaderboard. ---

What I am trynna say is the test data doesn’t include such type of test cases. Because of which even wrong solutions also passed. So, “ **Test cases are not fine** ”. ---

There have been already many discussions regarding test cases being weak. It is not correct to add test cases and re-judge submissions after the contest. Infact, it is not correct to add test cases between the contest also. After getting AC, many people don’t bother to check/prove their logic during the contest. So adding test cases and re-judging won’t be fair. You might like [this](https://codeforces.com/blog/entry/89063?#comment-775058) comment. ---

Yeah, I can understand. Hope it will not repeat in future contests. 🙂 The same me thinking fairly 🤔 > [@LUNCHTIM - Editorial](https://discuss.codechef.com/t/lunchtim-editorial/87198/28): > > It clearly states that Proper testing was not done on this problem before the contest started. The worst input for an O(N^2) solution is N = 10^5 and a\_i = k\ \forall\ i\isin[1, N], where k is some constant. If they had tested this input against an O(N^2) solution, there would have not been such a huge number of accepted submissions past night. It is not fair to rejudge these submissions because the contest ended. If they (organisers) had realised about it during the contest and made an announc… ---

Please consider removing your template when you share code on a public forum. It can be annoying for viewers to scroll 50 lines of gibberish just to check a couple of lines of actual code.
