@Satielo, that error message is confusing. I've reopened this issue so the test code can be fixed. Your code is failing on the random tests. I don't know why without seeing your code. If you do post it in the discussion, then please mark it as spoiler. We'll get the test code updated so it's output is more useful.

@suic, please see the issue I opened above.

I don't understand the problem description. However, what if the problem is: your solution didn't pass all tests, so it's not correct. I bet that this is the case. Try to paste it here and mark it as spoiler.

Regards,

one and two are variable, not values

random tests are in place to prevent hard-coding

This is likely an issue with the server. Please try again.
