I recently tried a problem, my code works well in cases where it was presented as an input sample , but failed when I sent it, and I still have not found any errors. So I really hope that some online judges who give me all the test cases use his engine so that I can find out the details when it reports such as WA , RE , OLE .Or This can give me a report, at least , tell me that the code does not work, on what tests.
