On a contest page, it seems that even post-contest, if there are incorrect test cases but at least one is correct, the problem is marked solved like so:
It's the same on the problem's My Submissions page.
However, if you look at my submission, I have nine incorrect test cases.
Is this a bug or a feature, speaking objectively?
If it's a bug, I'll report it, and if it's a feature I'd like to know its purpose as it seems misleading to think you may have solved a problem when there could be incorrect test cases.
