Problem-Solving with Algorithms and Data Structures using Python was designed to cover data structures from a practical point of view, with as many complete examples as possible. The data structures shown in this book are the most efficient, elegant, and robust designs. This textbook is designed to serve as a text for the first course on data structures and algorithms. In this book, we cover abstract data types and data structures, writing algorithms, and solving problems. We look at several data structures and solve classic problems that arise. The tools and techniques that you learn here will be applied over and over as you continue your study of computer science.
