I want to report wrong constraints / incorrect test cases in wakeup sid question(IMECO5D).
I have gone through accepted submissions of others and noticed that those who didn’t assert the constraint 0 <= L + R <= N - 1, got their answers accepted.
I ensured that constraint and got Wrong Answer.
I also found that many bruteforce solutions were accepted and some other solutions that didn’t handle integer overflows were also accepted. But according to the given constraints, they should result in Time Limit Exceeded or Wrong Answers.
So either this question must be removed or all the submissions must be rejudged with proper testcases.
Such a ridiculous waste of time, for a contest whose organisers don’t even care to check there test cases (even on informing them about the mistake) and whose toughest problem passed with brute solutions.
@sid55 I looks like that only your pc shows server problem every website. Instead of admitting mistake only finding out codechef / codeforces server problems. If there was actually a server problem then you should have contacted @admin to resolve issue at earliest.
“So bear with the issue” why ??
We are here to solve questions not regret after contest due to mistake of tester/setter. Poor contest. I’m happy that I have not participated in the contest.
I am the manager of IEMCO. Sorry for the delay in rejudge, I was stuck with some personal work as I have already mentioned. There was a bug in one of the test files of IEMCO5D (Wake Up Sid) which I didn’t catch with my assert statements due to the WA > RTE display preference. The rank list has been updated. The management team will soon be sending the prizes.
Shout out to @achaitanyasai for pointing out the possible bug in the test-cases.
Sorry for the inconvenience and delay and thank you to everyone for participating.
I have seen that @admin has submitted the code: https://www.codechef.com/viewsolution/18333107 to check the constraints in practice. It got Wrong Answer. But your code still gives SIGABRT. However, if I comment the print statements, your code also gives Wrong Answer.
So is the display preference of Wrong Answer > Runtime Error?? (I mean if the same code got Wrong Answer on some test files and RTE on some other files, does verdict displayed is Wrong Answer)?
Hey @achaitanyasai, @vaibhav138, @meooow, I am the manager of IEMCO… I believe that if there is really an issue, we probably didn’t catch it due to the WA>RE display preference thing. None of my assertions gave an RTE. Our team also received an email from CodeChef admin regarding this today. I will have all the files checked again and rejudged. Just give a bit of time, as I am stuck with some work. I will ensure that the prizes are distributed only after correcting errors and rejudge (if it is to be done). Just asking for a small amount of time due to personal work. Hope you guys understand.
