I often get Wrong Answer in competitions, and when checking the editorial afterwards am still not sure why my answer was in fact wrong. I often think it’s just one edge case or something that’s missing, but am not sure what it could be. I do these challenges casually and cannot invest the time into going deep into detail and comparing the execution of the two problems, so unfortunately I end up lost having no idea why my answer was wrong.
In these cases I end up adding an “answer” to the editorial asking somebody for an example input that would cause my program to generate a wrong answer, but of course this process is convoluted and unlikely to turn up a response.
Since code is already being provided in the editorials, why not also provide the test cases? This will greatly help users debug their programs and learn from their mistakes. I don’t think it impacts cheating at all because people had access to the code anyway, so if they’re interested in cheating the test cases will not be of any use to them.
What do we think? Can this suggestion be adopted?
