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.
