商品描述


Description

In this second edition of his successful book, experienced teacher and author Mark Allen Weiss continues to refine and enhance his innovative approach to algorithms and data structures. Written for the advanced data structures course, this text highlights theoretical topics like abstract data types and the efficiency of algorithms, as well as performance and running time. Before covering algorithms and data structures, the author provides a brief introduction to C++ for programmers unfamiliar with the language. All of the source code will be available over the Internet. Dr. Weiss also distinguishes the book with his clear, friendly writing style, logical organization of topics, and extensive use of figures and examples that show the successive stages of an algorithm.
