Hello,
Yesterday during CFR #429, I something magical thing happened to me.
Just before the end of contest, somehow my problem D was submitted and accepted!!!!
I already gave up the problem D and E due to the hardness (as usually), and I was trying to fix my hacked problem B. I think someone's submission was counted to mine, but at the end system judged that I cheated and copied :(
Is there someone else who have seen this issue?
I hope the admin will fix it, and rejudge my submission.
This is the submission that submitted on behalf of me. the source code and template is not mine at all!!!

What about your problem B and C
Problem A,B,C are fine. Those are my submissions. But there is a submission of B which I not sure. I assume there is a problem in the authentication system.
