When I was submitting the problem D in round #371, I clicked the "Choose File" button and selected my code.↵
↵
Before the submission, I read my code another time, found a bug in my code and fixed it. And then I clicked the "submit" button.↵
↵
But it turned out that my solution got wrong answer on pretest 4. I stress-tested my solution, and found it passed the big random data. I was really shocked. umm... Maybe my solution failed on some small testcases. So I tried many ways to generate testcases. But my solution was right on all the testcases I generated.↵

After struggling for about 40mins, I gave up and submitted it again. It passed all the pretests.↵
↵
I compared two codes, and just found I submitted the old version (before fixing the bug) at first time.↵
↵
After asking my roommate, he said when you clicked the "Choose File" button, it would upload the file instead of recording the path.↵

In the rest time of the contest, I tried to solve problem B and E but failed.↵
