Hi all, Apologies for the weak test cases in the problem CHEFSHIP. Here’s what actually happened. After preparing and testing the problem, we observed that there’s a need to reduce the load on the servers. So, while making modifications for that, we missed out on including sufficient testcases to break the brute solution. Sorry for the inconvenience caused.

Hi all, Test cases are updated. We can’t rejudge the contest solutions but in practice, you will have new test cases.

Yes, it was a mistake. We had anti tests for the brute forces. But we had only one such test in a file which surely was not enough to stop them (we thought it was enough). It was also partly due to me asking to try to reduce the test files and constraints a bit to reduce load on servers. We reduced constraints on sum of lengths after everything was prepared.We messed up somewhere around there. Author is updating tests for practice version of the problem.

Apologies again for the issue.
