# Algorithms and Data Structures

Below is your roadmap to master Data Structures and Algorithms, and become a great Problem Solver. Most textbooks do a phenomenal job at giving you great theoretical knowledge but often lack implementation details and hands-on coding experiences. TheAlgorist.com will bridge that gap. What makes this course different is our pragmatic approach to give you an in-depth knowledge on practical applications of each and every data structure and algorithm by solving real-world problems.This course will also help you with preparing for Coding Interviews at all kinds of tech companies including big tech companies and tech start-ups.
