Amazon Software Development Engineer (SDE) interview questions

The first question was to print all the subarrays in an array whose sum is 0, I explained the interviewer my approach and did code it.The second question was https://www.geeksforgeeks.org/problems/police-and-thieves--141631/1.In which I fumbled in the beginning as I have not seen this before, and was able to come up with all the approaches as the interview went on.But unfortunately, I was rejected.
