The book is good. It explained algorithms with a light language. I learned one thing or two with this book. There is a part when the author talks about electronics, it might be boring for someone else.
I picked up this book relating my current ambition to understand DS and algorithms without code but the book went all over but not dealing the subject in depth. The low level concepts that are discussed, though are a good connected topics - I think there are several books that explain these concepts in further detail. At the end of it, I didn't find the book either as a refresher for my current DSA knowledge or something that strengthens my DSA knowledge
This book aims to be a cursory tour of data structures and it doing so, managed to be filling with things that I mostly already knew. Even with that being said, the material was covered so lightly that I would say a couple evenings spent perusing wikipedia would be time better spent. Add to that that each chapter seems to begin with a \"And now I will introduce you to X\" and end with \"...now that you should be familiar with X\". I do not believe that I could recommend this to anyone.
This book contains a surface level view of some concepts in data structures and algorithms. It does not dwell much on any implementation. It reads like a collection of blog posts. I would only recommend this to beginners who need a quick overview of these topics. Look elsewhere for deeper understanding.
