Hi, The judging is done automatically on all problems. When there are multiple correct outputs, there is a program that looks at a given output to decide whether it is correct or not, not a human judge. So, even when practicing on old problems, you should get a valid judgement of your output regardless of the problem type (single-correct-output or multiple-correct-output).
I agree with Bart, it is highly unlikely that there is a bug making a correct output being judged as incorrect because it was tested thoroughly before the contest, and a lot of people used it without an issue during the contest. Unexpected bugs in code that a single person wrote, however, are more likely, so I would encourage you to check your code.
