It is also about Python. However, there is much more. The study of algorithms and data structures is central to understanding what computer science is all about. Learning computer science is not unlike learning any other type of difficult subject matter. The only way to be successful is through deliberate and incremental exposure to the fundamental ideas. A beginning computer scientist needs practice so that there is a thorough understanding before continuing on to the more complex parts of the curriculum. In addition, a beginner needs to be given the opportunity to be successful and gain confidence. This textbook is designed to serve as a text for a first course on data structures and algorithms, typically taught as the second course in the computer science curriculum. Even though the second course is considered more advanced than the first course, this book assumes you are beginners at this level. You may still be struggling with some of the basic ideas and skills from a first computer science course and yet be ready to further explore the discipline and continue to practice problem solving. We cover abstract data types and data structures, writing algorithms, and solving problems. We look at a number of 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.

    With this guide, pioneering Go programmer Mark Summerfield shows how to write code that takes full advantage of Go's breakthrough features and idioms. Both a tutorial and a language reference, "Programming in Go" brings together all the knowledge you need to evaluate Go, think in Go, and write high-performance software with Go. Summerfield presents multiple idiom comparisons showing exactly how Go improves upon older languages, calling special attention to Go's key innovations. Along the way, he explains everything from the absolute basics through Go's lock-free channel-based concurrency and its flexible and unusual duck-typing type-safe approach to object-orientation. Throughout, Summerfield's approach is thoroughly practical. Each chapter offers multiple live code examples designed to encourage experimentation and help you quickly develop mastery. Wherever possible, complete programs and packages are presented to provide realistic use cases, as well as exercises. Coverage includes:-- Quickly getting and installing Go, and building and running Go programs -- Exploring Go's syntax, features, and extensive standard library -- Programming Boolean values, expressions, and numeric types -- Creating, comparing, indexing, slicing, and formatting strings -- Understanding Go's highly efficient built-in collection types: slices and maps -- Using Go as a procedural programming language -- Discovering Go's unusual and flexible approach to object orientation -- Mastering Go's unique, simple, and natural approach to fine-grained concurrency -- Reading and writing binary, text, JSON, and XML files -- Importing and using standard library packages, custom packages, and third-party packages -- Creating, documenting, unit testing, and benchmarking custom packages

    David A. Kessler explains why Americans suffer in unprecedented numbers from obesity, heart disease, diabetes, and other debilitating illnesses, and offers concrete solutions for reducing cardiovascular problems, keeping weight off, and curtailing chronic disease.The American body is in trouble. Heart disease is the number one cause of death in the United States today, and millions are plagued by conditions like obesity and diabetes. But we have the answer to improving health and longevity: 1) cut out fast carbs (processed foods); 2) reduce saturated fats; 3) exercise regularly.Though the solution is simple, the difficulty lies in the food we eat. Multi-billion-dollar processing plants and food manufacturers dot the heartland and work to increase the profits of the industrialized farming business—Big Agriculture—that produces excess corn and wheat. Today, we are being fed highly palatable, ultra-processed carbohydrates as food products—fast carbs—that are often marketed as “healthy.” Fast carbs are primarily starches and sugars produced during food processing and are present in much of what we eat. By destroying the healthy structure of whole food and increasing the amount of rapidly digestible starch it contains, these products bypass our body’s metabolic pathways. When combined with the ill-effects of saturated fats, we are putting ourselves on a collision course with weight gain, insulin resistance, digestive issues, heart disease, and more.The problem is, most of us don’t know where these fast carbs and saturated fats lurk in our daily diets. Accessible and eye-opening, Fast Carbs, Slow Carbs provides the information we need to understand exactly what we are eating—and to learn the truth about what it being sold to us as “healthy” food. Rising above the confusing range of specific popular diets—Keto, Paleo, Mediterranean, Vegan, Vegetarian—Dr. Kessler gives us an achievable baseline that can set us on the path to better health.
