I have tested my code for many cases on my computer and it gives correct answer for all of them, but the online judge is not accepting it. Can somebody help me find the error in this code? Please tell me if you know some tricky test cases which are likely to make people get wrong answers.
I think the online judge should tell us which test case is giving wrong answer.
Some test cases I tried and their answers:
