Very weak test cases in CHEFSHIP
If this passes then idk for what the tester @raja1999 is being paid for :frowning:
@rishup_nitdgp @teja349 @admin

This is being very often now. I think admins should make some strict rules for testers.
In april long challenge STRNO test cases are weak.
I myself hacked two problems in may long challenge ( and reported in comments as well) (but the hack’s were not very trivial so refrained from reporting through email and discuss ). And test files of 3 problems were changed during contest.

I would like to request @rishup_nitdgp to update test files for practice section at least now.


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.


Thank you for the clarification and thanks to the setter for updating test files :slight_smile:
