Description
Content

The book focuses on algorithms written in Java and presents several classic algorithms, but the primary goal is to introduce algorithm analysis, and then allowing the reader to be able to compare and evaluate the complexity of algorithms. In addition, the book treats the classic data structures such as lists and trees and shows how these data structures can be implemented in Java.
