Clarification regarding test cases given in question

I had a doubt in one of the sample test case given for a particular question in July Long Challenge 2020. I think its wrong and I also commented about it. But nobody has answered my query till now. What should I do? In codeforces all queries receive prompt reply.

Please don’t report me as I am new here and still understanding the rules.

They might be busy and in case you don’t receive a reply over 10 days, the test cases are correct.

But isn’t it their responsibility to provide explanation for test cases in the question itself?

No, sometimes giving explanation of samples gives some spoiler regarding the solution. So, they don’t provide it make solution harder to crack.

Okay. Thank you :grinning:
