Hi team, I just foudn out my submission to problem A passed the pretest but failed the system test because of compilation error.

I think there is nothing wrong with my code and it is supposed to be the system issue.

My ratign is -150 because of this error.

Could anyone tell me what I am supposed to do? Is there anyway to get my rating back? I feel really upset about this...
