This book prepares students for the world of computing by giving them a solid foundation in the "science" of computer science - algorithms. By taking an algorithm-based approach to the subject, this new book helps readers grasp overall concepts, rather than getting them bogged down with specific syntax details of a programming language that can become obsolete quickly. By working with algorithms from the start and applying the concepts to the real world, students will understand the power of computers as problem solving tools and learn to think like programmers.
