Book Review: “Grokking Algorithms: An Illustrated Guide for Programmers and Other Curious People” by Aditya Bhargava

“Grokking Algorithms” by Aditya Bhargava is a refreshing and approachable take on the often intimidating subject of algorithms. Published in 2016, this book aims to demystify algorithms for beginners and those not formally trained in computer science by using simple language, clear explanations, and a wealth of illustrations. Here’s a detailed review of this engaging educational resource.


The book is designed with the novice in mind, covering fundamental algorithms and concepts in computer science. It spans a range of topics from basic data structures (like linked lists and trees) to more complex algorithms (like sorting, searching, and graph algorithms). Each chapter focuses on a different algorithm or data structure, explaining its mechanism, its use-cases, and how to implement it effectively.

Content Quality

Aditya Bhargava explains complex concepts in a way that is accessible and engaging without diluting the core subject matter. The text is interspersed with diagrams, cartoons, and pseudo-code that not only make the learning process enjoyable but also help reinforce the material. This visual and conversational style is particularly effective for those who might find traditional programming books dense or intimidating.

Key Lessons and Features

  • Algorithm Efficiency: The book introduces Big O notation early and uses it throughout to discuss the efficiency of various algorithms.
  • Recursion: It breaks down recursion in a highly digestible manner, helping readers understand both the power and pitfalls of recursive programming.
  • Sorting and Searching Algorithms: These fundamental algorithms are covered in depth, with visual aids to help readers understand how each algorithm progresses step-by-step.
  • Graph Algorithms: The treatment of graphs — from basic traversal techniques like breadth-first and depth-first search to Dijkstra’s algorithm — is particularly clear and practical.
  • Practical Applications: Each algorithmic concept is tied back to real-world applications, demonstrating why learning these concepts is useful.


The book does an excellent job of balancing theory with practical application. Code snippets are provided in Python, which is known for its readability and simplicity, making the examples easy to understand and experiment with. The end of each chapter includes exercises that encourage readers to apply what they’ve learned and deepen their understanding.


“Grokking Algorithms” is ideal for beginners in computer science, programming students who need a refresher on algorithms, or even self-taught programmers who want to formalize and enhance their understanding of algorithmic thinking. It’s also a great resource for educators looking for a way to introduce these concepts in a more engaging and accessible manner.


“Grokking Algorithms” stands out as a primer on algorithms that is not only informative but also exceptionally reader-friendly. Aditya Bhargava’s approach of using illustrations and simplified explanations makes this book a valuable resource for anyone looking to get a good grounding in algorithms without getting overwhelmed by complexity.

Overall, this book is highly recommended for its educational value, clarity, and the unique way it makes learning algorithms fun and interesting. Whether you’re a programming novice or just looking to brush up on your algorithmic knowledge, “Grokking Algorithms” is an excellent choice.
