数据结构课程的实践性是很强的， 不只是要掌握理论上的方法， 还必须将这些方法应用到程序设计的实践中去。 鉴于此， 作者编写了本书。 本书没有详细介绍各种数据结构的原理， 而是重点介绍各种数据结构的实现方法， 及相应的具体程序代码。(The practice of data structure course is very strong, not only to grasp the theoretical method, but also must apply these methods to the practice of programming. In view of this, the author has written the book. This book does not give a detailed introduction to the principles of various data structures, but focuses on the implementation of various data structures, and the corresponding specific program code.)
