Even though my solution has been accepted as correct by the system, sometimes it fails when i try to resubmit it. I was trying to fix my code that had failed in two test cases, and i clicked to submit button for no reason and it has been accepted. Issue is still there when i resubmit it. It is accepted like half of the time. I am not sure if it is a problem but I think there might be an issue with the random test cases that does not check all the desired situations in the description. Can you check this situation? Thanks, in advance.
