Amazon Internship Software Engineer interview questions

Answer to a question most likely leads to a new question relative to the answer. Technical part was difficult.Make sure you deeply understand data structures and go through intense problem solving exercises before interview ,will help make interview seem a lot easier.

There were two questions of medium difficulty, I was able to solve one question completely and one I was able to pass half of the test cases. The interview was 1 hour so solving two questions was a bit difficult.
