What is this?

This material categorizes coding interview problems into a set of 8 patterns. Each pattern will be a complete tool - consisting of data structures, algorithms, and analysis techniques - to solve a specific category of problems. The goal is to build an understanding of the underlying pattern so that we can apply that pattern to solve other problems.

Complete guide and roadmap for SDE I and SDE II algorithm round.
