I give this book only 2 stars. This book is not for students taking their first course in data structures. However, I first encountered it as a required text for an introductory Data Structures course that I took. This book is not an easy nor an enjoyable read. It does not contain nearly enough visual aides i.e., graphics, screen shots, diagrams to help a reader develop a mental image of abstract data structures. It is far too technical to be used as an introductory text to Data Structures. It is a colorless, lifeless presentation of a subject that actually can be quite fun and interesting. How can a book on Data Structure be fun or interesting...Please see my review of "Data Structures And Algorithms in Java" by Robert LaFore. Mr. Lafore's book is OUTSTANDING! It has great graphics, simple explanations, a great Table of Contents, and Index. I bought it and it was instrumental in my getting a "A" in the course. I recommend you buy it instead of Mr. Weiss's product.
