在Java环境下，向计算机领域的读者介绍基础的算法与数据结构。-Before there were computers, there were algorithms. But now that there are computers, there are even more algorithms, and algorithms lie at the heart of computing.

This book provides a comprehensive introduction to the modern study of computer algorithms. It presents many algorithms and covers them in considerable

depth, yet makes their design and analysis accessible to all levels of readers. We

have tried to keep explanations elementary without sacrificing depth of coverage

or mathematical rigor.
