本书是作者编程经验的结晶，由发表在杂志上的专栏文章构成，每一章内容相对独立，但都是编程过程中的有机组成部分。本书内容包括问题定义、算法、数据结构、程序验证与测试、程序优化与效率问题，以及这些技巧在排序、查找和字符串处理等方面的几个实际应用。本书每章末尾都附带有相关内容的问题，附录中给出了一些问题的提示和解答。仔细思考问题或与同事进行讨论，可以巩固所学知识，将作者的经验应用到自己的编程实践中。-This book is the author of the crystallization of programming experience, published in the journal by the column consists of the contents of each chapter is relatively independent, but they are in the process of programming an integral part. The book includes problem definition, algorithms, data structures, program verification and testing, process optimization and efficiency issues, as well as these skills in sorting, string search and deal with several aspects of practical application. The book comes at the end of each chapter has relevant content issues, the appendix gives some tips and answers to the problem. Think carefully about questions or discussion with colleagues, you can consolidate the knowledge acquired will be applied to the author

采用来唯一地确定每一个非零元素，其中row、col、value分别表示非零元素在矩阵中的的行 下标、列下表和值。各数组元素的三元组按在原矩阵中的位置以行优先的顺序依次存放。在稀疏矩阵的十字链表 表示中，矩阵的的每一行设置为一个带附加头结点的循环行链表，每一列也设置为一个带附加头结点的循环列链 表。基于三元组及十字链表的稀疏矩阵乘法
