Algorithms Every Programmer Should Know - by Aniket Wattamwar (Paperback)

Book Synopsis

Classic algorithm textbooks are well known for encyclopedic depth, mathematical rigor, and extensive use of pseudocode to explain complex algorithms. Or, put plainly, they can be dense, boring, and hard to understand. This book takes a more human approach. This highly approachable book drops you straight into a realistic reading group, letting you listen in as three interested individuals argue, question, and reason their way through some of the most important algorithms in computer science.

Each chapter tackles one algorithm from the ground up. You'll build your intuition through relatable analogies and back-and-forth discussion, then see the idea applied to real-world systems like routing, scheduling, string search, caching, and optimization. Once you've built your mental models, you'll implement each algorithm in Python. Seeing your algorithms in action ensures you understand both how an algorithm works and why and when to reach for each one.

The algorithms you learn go far deeper than the usual interview list. Discover Gale-Shapley for stable matching, Rabin-Karp and Knuth-Morris-Pratt for string search, the Hungarian algorithm for assignment problems, Push-Relabel for network flow, Bron-Kerbosch for finding cliques, Adaptive Replacement Cache for smarter memory management, and more. Each chapter closes with reflective questions, real-world applications, and a concise summary you can return to before an interview or a design review.

You don't need to read the book cover to cover, you can dip into any chapter as you need! Self-taught developers will get intuitive explanations that go deeper than rote memorization, students will find a friendly companion to their coursework, and working engineers will walk away with sharper mental models for choosing the right tool for the problem in front of them. Plus, Python notebooks and supplementary explainer videos make sure the ideas stick.
