## 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.**

## Content overview

- Sliding Window Pattern, more is being added.
- Arrays and Strings (Coming soon)
- Recursion overview and recursion problems (more) coming soon
- Linked lists overview and problems
- Stacks overview and stack problems and Queues (coming soon)
- Binary Search overview and Problems (more coming soon)
- Trees overview and tree problem
- Graphs overview, graph bfs and dfs and Graph Problems,
- Heaps overview and heap problems and 2 heaps problems.
- Greedy algorithms
- Dynamic Programming
- Bit Manipulation (With C/C++) (coming soon)
