Data Structure and Algorithms in Ruby, First Edition

This book introduces you to the world of data structures and algorithms. Data structure defines the way how data is arranged in computer memory for fast and efficient access while algorithm is a set of instruction to solve problems by manipulating these data structures.
Designing an efficient algorithm is a very important skill that all computer companies e.g. Microsoft, Google, Facebook etc. pursue. Most of the interviews for these companies are focused on knowledge of data structure and algorithm. They look for how candidates use these to solve complex problems efficiently, which is also very important in everyday coding. Apart from knowing, a programming language you also need to have good command on these key Computer fundamentals to not only qualify the interview but also excel in the top high paying jobs.
This book assumes that you are a Ruby language developer. You are not an expert in Ruby language, but you are well familiar with concepts of class, references, functions, list, tuple, dictionary and recursion. At the start of this book, we will be revising Ruby language fundamentals that will be used throughout this book. We will be looking into some of the problems in Lists and recursion too.
