This practically-focused textbook presents a concise tutorial on data structures and algorithms using the object-functional language Scala. The material builds upon the foundation established in the title Programming with Scala: Language Exploration by the same author, which can be treated as a companion text for those less familiar with Scala. Topics and features: Discusses data structures and algorithms in the form of design patterns Covers key topics on arrays, lists, stacks, queues, hash tables, binary trees, sorting, searching, and graphs Describes examples of complete and running applications for each topic Presents a functional approach to implementations for data structures and algorithms (excepting arrays) Provides numerous challenge exercises (with solutions), encouraging the reader to take existing solutions and improve upon them Offers insights from the author’s extensive industrial experience Includes a glossary, and an appendix supplying an overview of discrete mathematics Highlighting the techniques and skills necessary to quickly derive solutions to applied problems, this accessible text will prove invaluable to time-pressured students and professional software engineers.
