Now that people are aware that data can make the difference in an election or a business model, data science as an occupation is gaining ground. But how can we get started working in a wide-ranging, interdisciplinary field that’s so clouded in hype.

This practical, hands-on guide to data structures and algorithms goes beyond theory and will help us vastly improve your programming skills. By reading this Data Science book, you’ll learn how to use hash tables, trees, and graphs to improve the efficiency of your code, with practical exercises in each chapter so you can practice what you have learned before moving on to the next topic. While algorithms and data structures are often presented as theoretical concepts, this book focuses on mastering these concepts so that you can make your code run faster and more efficiently.
