Leetcode Coding Challenge Using Lambda

Leetcode Coding Challenge Using Lambda is a code challenge in our team. It was an amazing learning experience and I am happy to walk through how I did it. I decided to come up with some guidelines so I don't over-engineer this and end up building a Frankenstein out of it. The system consists of four key functionalities based on which these modules are designed: registration & sign-in, compile & Execute, compile and execute code. The whole system should be implemented in 3 to 4 days.
