T(n) = 3T (n/2) + n2 => T (n) = O(n2) (Master Theorem Case 3.a) sorry couldn't be bothered making the n squared or the theta symbol because I lost the will to live. There are 20 complex functions like this on one page which is in the first chapter. Do not buy this book unless you have a degree in mathematics.
I have worked as a developer with very talented junior and senior developers for many years. Many of them can explain these concepts in English and have never resorted to such equations.
Please change this title as it has not been made easy. I would call this book Data structures and algorithms from a mathematicians perspective. (not a developers)

Must Have book for DS and Algorithm2015年10月4日にインドでレビュー済み
If you want to clear your basic ideas or want a book if everything is in concise manner you should go for this book. The book is really interesting and has got a large varieties of problem.This book will make you understand the stuff much more.
Paper quality is not good. Also, the book size makes it unweildy to read. Didn't find the approach used by the author to teach DS & Algos useful. Looks like compiled without much thought. Not in class with CLRS or Prof. Sedgwick's Algorithms
I am a software profession and just for polishing my knowledge I picked up this book. They made a great hue and cry for this book but I personally did not find this book quite helpful. Author has just touched the topics and most of the time almost all the time he given us the small intro instead of giving concepts. They way he provides the solution for problems is weird and terrific.
