Build Your Algorithm Skills [PDF ebook] 

From the simplest applications to the largest networking centers, algorithms are the heartbeat of computer science. The beauty of computers is their ability to automate processes, and algorithms are the tools coders use to make that possible. They employ core computational thinking skills, including logic and problem solving to make software tick. Through a series of thoughtful activities, readers will learn what algorithms are, what they are used for, and how to make their own algorithms using pseudocode and flowcharts. These interactive, game-like projects provide an accessible path to understanding algorithms, even with little or no computer science experience.
