Your solution was throwing when it shouldn't, and tests would pass you when that happened, thus causing you to pass things you shouldn't have.

This is no longer the case. So this is at the very least partially solved.

Then another matter is whether the random tests cover enough special cases and such, but I'm choosing to interpret this issue as having to do with the incorrectly handled exceptions. Do create another issue if you find that tests still exhibit similar behaviour after having fixed your exceptions. Ideally identify what kind of tests would be needed as well, which may be easier for you to do since you know what's wrong in the code.

is genius bro

I've got the same problem as others
C# 10.0

Test Failed
Applied Rank; -1; Expected progress: 21, Actual: 20
Expected: True
But was: False

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.

Because "c" has no votes in the first round, they are eliminated first.

Thanks, your description really helped me
