As all of us here want to learn from mistakes, is it feasible for codechef to upload all test cases for the problems along with editorials after contests are over so that we can understand which kind of corner cases we were missing and learn from them.
This request has been declined many times in past. And most probably their stand will be same this time also. And I’m neutral on this.
Yes, Now I am satisfied with their concern that - someone can clone the problem
If you can see code solutions, what’s the problem with getting to know the test cases where your program fails. Problems can be cloned anyway, not giving testcases where your code fails is just making it worse for you to learn where you fail; speaking from personal experience.
