Why is there so little information when the uploaded solutions end up wrong? Shouldn’t we be able to get a bit of input on what went wrong by, for example, receiving the test-case in which it failed?
Otherwise, we end up blindly trying to fix a problem that we have no idea what it is.
This would make sense if we had a system that rewarded users for having a near-correct solution. An example of this is an exam in some class. The student doesn’t know the solution when he is doing the exam, but he’s score is given based on how good is solution was, even if it ended up not being completely correct.
This scoring system, however, does not provide any input on what you did wrong and does not provide any score unless you successively completed the problem.
