It would be very good if CodeChef could provide a detailed set of test case for a given problem and at what particular test case did a particular code fail. This would be a really good initiative on your part to help people in improving the tiny small errors that are really-really hard to spot and a…

I tried nearly 10 to 15 different test cases and it is working fine for each of them. If possible just let me know the input for which my program fails as I have tried everything from my end. I only want to know about the input so I could modify my program accordingly.

Here- Input 1 4 NNIN Your Output NOT SURE Expected Output INDIAN It is an Indian as it both performs the ‘I’ gesture- which no foreigner does as told by problem statement.

I wont be able to learn if I keep making the same mistake over and over again. I don’t want test cases during a competition. All I need is one or two failing test cases in the practice section so I can debug my code and see where it is going wrong and see what mistakes I made so that I can rectify i…

It’s not exciting, it’s frustrating. I have a solution to a problem that appears to be the same algorithm as another solution that got the right answer, yet I have the wrong answer. I’ve generated several testcases, but haven’t been able to figure out what is wrong with my code. Without seeing the f…

[image] violetval: On Codeforces, for example, someone occasionally spots an error with a testcase, and it gets corrected. There’s no way that can happen when you don’t reveal the testcases even after the contest. People identified that the testcases were wrong in a recent lunchtime; see e.g. …

If you are really desparate in knowing the the test case, what you can do is take an accepted solution and generate some random cases and check it on both codes . Use some script so you don’t have to manually input the cases each time

I use this for generating sample cases to run my code on. I write a bruteforce code, and an optimized code (which I have to debug) and run randomly generated Testcases on both. The cases which give different answers usually point out the error.

Anyone who finds not knowing the testcases exciting can simply choose not to look at the testcases. Providing testcases allows those who find not knowing testcases exciting to keep their excitement, while also allowing those who find it frustrating to minimize their frustration.

Thank you. That was actually helpful.

Will CodeChef provide test cases
