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

假设一个文件中出现了8种符号S0,SQ,S2,S3,S4,S5,S6,S7,那么每种符号要编码,至少需要3bit。假设编码成000,001, 010,011,100,101,110,111。那么符号序列S0S1S7S0S1S6S2S2S3S4S5S0S0S1编码后变成 000001111000001110010010011100101000000001,共用了42bit。我们发现S0,S1,S2这3个符号出现的频率比较大,其它符号出现的频率比较小,我们采用这样的编码方案:S0到S7的码辽分别01,11,101,0000,0001,0010,0011, 100,那么上述符号序列变成011110001110011101101000000010010010111,共用了39bit。尽管有些码字如 S3,S4,S5,S6变长了(由3位变成4位),但使用频繁的几个码字如S0,S1变短了,所以实现了压缩。对于上述的编码可能导致解码出现非单值性:比如说,如果S0的码字为01,S2的码字为011,那么当序列中出现011时,你不知道是S0的码字后面跟了个1,还是完整的一个S2的码字。因此,编码必须保证较短的编码决不能是较长编码的前缀。符合这种要求的编码称之为前缀编码。要构造符合这样的二进制编码体系,可以通过二叉树来实现。-Suppose a file appears in eight kinds of symbols S0, SQ, S2, S3, S4, S5, S6, S7, then each symbol to be encoded, at least 3bit. Suppose encoding 000,001, 010,011,100,101,110,111. Then the symbolic sequence S0S1S7S0S1S6S2S2S3S4S5S0S0S1 encoded into 000001111000001110010010011100101000000001, sharing a 42bit. We found that S0, S1, S2 these three symbols the frequency of relatively large, the other symbols the frequency is relatively smal

1 创建给定图的存储结构,从邻接表和邻接矩阵两种存储方式中选择一种。
2 对所创建的图进行深度和广度优先搜索遍历,给出遍历过程中的顶点序列。
3 求图的最小生成树,按构造顺序输出边的序列。(两种方法都要求!)
-Create a storage structure of a given graph from the adjacency list and adjacency matrix are two ways to choose a store. Two pairs of maps created by the depth and breadth-first search traversal, given the culmination of the process of traversal sequence. 3 order to map the minimum spanning tree, according to the order of the output side of the sequence structure. (Both methods require!)
