Most of the time I got the wrong anwers on hidden test cases like Wrong Answer on 91 test case (Test 2) or 2000 test case (Test 7) etc.
Sometimes after trying all possible corner test cases and some random test cases I am not able to find which type of test case give the wrong answer.
I will highly grateful to you if you can give me some ideas which are really helpful to find those hidden test cases.
Thank You.
Have you tried stress-testing?
Are you talking about stress-testing in software testing? then how it is helpful. And if it is something else Please can you tell me something about this.

In sublime Text there is a package named fastolymp coding in which you can do stress testing with correct solution and you will be able to find a testcase where your code fails Youtube link hope this helps ;}
