Algorithms and data structures are much more than abstract concepts. Mastering them enables you to write code that runs faster and more efficiently, which is particularly important for today??s web and mobile apps. Take a practical approach to data structures and algorithms, with techniques and real-world scenarios that you can use in your daily production code, with examples in JavaScript, Python, and Ruby. This new and revised second edition features new chapters on recursion, dynamic programming, and using Big O in your daily work.


Use Big O notation to measure and articulate the efficiency of your code, and modify your algorithm to make it faster. Find out how your choice of arrays, linked lists, and hash tables can dramatically affect the code you write. Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks and mapping software. You??ll even encounter a single keyword that can give your code a turbo boost. Practice your new skills with exercises in every chapter, along with detailed solutions.


Use these techniques today to make your code faster and more scalable.

    Reviewed in Canada on June 7, 2024

    The book offers superb insight into some of the most fundamental data structures and algorithms. However, don't expect to go too deep into any particular topic.

    A strong mathematics background is not required to read this book. Each chapter introduces the topic in plain language and builds upon the core ideas without overcomplicating them with too much mathematics.

    Sample code is provided in the book, albeit in a random assortment of Ruby, Python, and JavaScript, but separate editions of the book stick to a single language.

    The end of each chapter contains exercises which vary in difficulty. Answers are provided at the back of the book. Exercises sometimes require coding or drawing in addition to thinking.

    Although I felt that a few topics could have been added to the book (merge sort, topological sort, union-find, minimum spanning trees, Prim's, Kruskal's), I won't take points off. Perhaps those topics will appear in a 2nd volume.

    Overall, this was a worthwhile purchase. The print quality was acceptable and the price was reasonable.

    I recommend this book to anyone, beginner or expert, to learn or refresh their knowledge of data structures and algorithms.

    5.0 out of 5 stars Great for self taught programmers
    Reviewed in Canada on December 20, 2021
    Verified Purchase
    As someone who taught myself to code as a kid, Ive often regretted never getting a formal CS degree because I missed out on some of the fundamentals. A lot of these are implemented for us in modern programming languages but they are important if you want to understand whats actually going on and also for understanding the performance of your own code.

    Ive tried a lot over the years to teach myself the common data structures and algorithms. Ive learned a bit here and there but I found this book finally made a lot of them click for me. It explains things so simply that when it comes to something like searching an array it seems too simple but makes more advanced topics really easy to understand.

    Also as another reviewer mentioned, the use of Ruby and Python (neither of which Ive used before) actually makes it easier to understand the topics because the code is less cluttered with boiler plate code. It makes it easier to understand the algorithms.

    What a great book. Highly recommend this for a developers must have book collection.

    This book is one of my favorites. The examples are in python, ruby and javascript.
    I was skeptical about that, but python and ruby turn out to be pretty good for learning the material
    without a lot of extra boilerplate like you'd get in java/C++.
    More importantly, the author makes it interesting and provides good end of chapter problems. You can only learn this stuff well by implementing a fair amount of it yourself.

    This book is good if you're curious on the theory behind data structures and algorithms. If you're trying to get practical experience using them, identifying applicable problems, or preparing for interviews, I would look elsewhere. Online courses with a built in editor served me far better than this book.

    The author does a fantastic job in covering a broad range of data structures and problem solving techniques. I work as a software engineer, and I don't consider myself great at data structures and algorithms. This book certainly improved my confidence and provided me a refresher of the common ones that I am aware of, and know well. Additionally, it also taught me new topics that I hadn't studied before.

    For some reason I see many people not recommending this book for beginners and recommending Grokking Algorithms instead. These people say this one is more advanced.

    I must say it's not! It's an amazing book, really well explained in layman terms. Illustrations are great and the play by play of algorithms is very efficient at helping you visualize the solutions

    It's much better than Grokking Algorithms, IMO

    The book is very comprehensive and easy to grasp, if youre a beginner I definitely recommend it. But the author has included examples from both Ruby, Python and JS, and as someone with 0 Ruby knowledge, reading and understanding Ruby examples can be difficult at times. If youre like me, I recommend buying this same books Python or JavaScript versions, as I also had to buy the Python version to grasp the material even better.
