I have recently completed the online assesment test of AMAZON. I have completed both the question and all the test cases ran perfectly fine. But still got the rejection. I am not sure what was the reason, were they not expecting to complete the both challeneges.

It's furstating when you have put lot of effort and time to prepare and then complete the test will 100% correct solution but still get the rejection without any reason.
