There was this competition yesterday named AARAMBH-2019. In one question to my surprise I received a TLE on submitting it, and after trying many approaches, I couldn’t get Correct Answer to the question. After the contest ended, this morning I again submitted the same solution. Guess what this time it passed with Execution Time of 0.0 Sec. Could anyone tell me why this happened?
The link to the question: CodeChef: Practical coding for everyone .
The link to my solution which got TLE: CodeChef: Practical coding for everyone .
The solution which was accepted: CodeChef: Practical coding for everyone .
There are no changes in both the solution.
This is indeed weird.
This is my guess to what happened:
- Your solution should receive TLE, as it did in contest:
for the text case T = 999;X=1,N=10^7 your program would complete in 1000 seconds. - While transferring to practice, the time limit became -1 seconds. This caused the TLE solution to be accepted. Probably because some unsigned to signed conversions.
Hi,
This is because the contest organizer had removed some test files during the contest. We have asked them for an explanation.
Cheers,
CodeChef
