I have tried my program on alot of test cases of mine. Its working perfectly. But when i submit my code. Then it fails on all of the test cases except the sample one..Do anyone have any idea about the testcases?

I want to see the test cases for which my solution failed.

What does easy mean? This has a 6% success rate.

Cannot contain duplicate??... Maybe

how do we get the test cases...my solution failing other than the sample one.
