Well yeah, I would guess contest authors are aware of codeforces rules...
Sure it is a false positive plagiarism detection issue. It happens rarely.
But did you read the comment from the system? It gives you a standard way to resolve such issues. No need to write posts like this.UPD: Sorry, I don't know why you didn't receive a message about the violation. I'll investigate it.I didn't get any message.
Hi went through your solution. I am unable to understand couple of things.
What is the purpose of substracting and adding 1 for upper k or lower k?
Thanks
Those are div floor and div ceil functions and they do exactly that. The inequalities for k come from requirement that solution is greater or equal to zero.
