As in codeforces , there is an option to view the testcases for which your code is not giving the right output. Is it possible that such an option can be made in codechef to? Or does there already exist one, If yes then how can i access it? I believe that it may help many people understand where there approach failed after the contest because its always not the case that your approach matches with the editorial. I know you can ask the same doubt in discussion but it would save a lot of time if the testcases were given since then we can check our codes ourselves. This is my suggestion. I would love to see your suggestions too.
