I was solving this problem, but when I tried to submit I got a strange error. The error is: Denial of judgement.
I tried submitting one more time but still got the same error. I opened my submission and saw that the code ran fine until test 38, where it says: verdict: Crashed. Here is a link to my submission.
Can any one help me or suggest something I can do?
UPD : It's fixed now thx.
I just resubmitted my AC solution and it got Denial of Judgement too. I guess the only thing you can do is wait :D
You get this error when e.g. model solution crashes. It's bug on Codeforces side.
