In this submission,I found that he used assembly to solve this problem.But I found that he never used assembly to solve any problem and we can find that he turn a c++ code into an assembly code.I think he can submit his c++ code but he didn't do it.So I doubt he copied other's code.

I have some questions about duplicate checking.

There are three records 137029080,137029028,137028914.

We can see 137028914 is the earliest,but it was wrong.

When the submitter corrected his code and resubmitted it,someone submitted the same code but it was also corrected,and we can see,because the other one was earlier,the other one didn't skip but he skipped.

I don't know if it is right and I want to know how to do when I was copied and mine wasn't right but the solution of the person who copied me is right.
