If a contestant submits several times a problem's solution that passes all pretests, then the last solution is considered as the contestant's verified solution for this problem. All other solutions will be considered as unsuccessful attempts.

This was my best performance and the moment I saw my rank fell down to 500+ I was shocked. You can imagine how badly it would hurt knowing that your best performance got ruined just because you didn't read the rules. I was speechless and so not happy with myself.

I know this rule is well thought. But isn't it unfair that a participant has to resubmit just to assure that his/her solution won't FST ?? I mean the participant wouldn't have resubmitted in the first place if he had gotten WA. So in my opinion the solutions should be treated in chronologicall order and the first code that gets AC should be counted.

But I guess this would lead to participants doing tons of resubmissions just to ensure FST... In the end I would highly suggest everyone to read the rules thoroughly.
