Hello everyone, I hope you are doing well

In today's contest , I solved problem C within one hour and got 827 points for that . At the end of the contest and exactly after 2 hours and 57 minutes, I thought that my solution for problem C may get TLE in main tests , so I submitted another improved solution and got AC for the pretests . But the problem is that I got 478 points on the problem and the 827 points had gone. And now after the system testing I got my first solution Skipped eventhough it got Accepted when I resubmitted it after the testing. I believe that this thing is unfair and I hope Codeforces try to solve this problem for us.

Thanks for your attention Good Luck
