大学计算机专业教材《数据结构》中栈的实验、练习源码(University computer professional teaching materials" data structure" stack experiment, practice source code)

说明：  一个实现外部排序的程序，其中gnerate.cpp为产生一个随机的文件，用于被排序。而caculate.cpp为外部排序程序。(A realization of the external sort program, which gnerate.cpp to generate a random file for be sorted. The caculate.cpp external sort program.)

说明：  数据隐私保护K-匿名问题的动态多次发布类似m-invarience算法(Data Privacy Protection K-anonymity problem on many occasions issued a similar dynamic m-invarience algorithm)

简单LR语法分析程序自动生成器的实现，可用作数据结构课程设计(LR (0) grammar analysis)

迷宫求解一般采用“穷举法”，逐一沿顺时针方向查找相邻块（一共四块－东(右)、南(下)，西(左)、北(上)）是否可通，即该相邻块既是通道块，且不在当前路径上。用一个栈来记录已走过的路径栈是限定仅在表尾(top)进行插入或删除操作的线性表。(Maze solving generally use the " exhaustive" one by one to find adjacent blocks in a clockwise direction (a total of four- East (right), South (down), West (left), North (on)) whether to pass, that the both channel blocks adjacent blocks, and not in the current path. Use a stack to record the path traversed stack is limited only in the tail (top) to insert or delete a linear form.)

1>实现可以随意浏览任一景点的介绍。（功能一） 2>可以给出任意两个景点的最短距离及其路线。（功能二） 3>可以查看任一景点热度，并可以对对所有景点热度（访问次数）进行排序。（功能三） 4>每个景点相关内容从文件读取，实现对文件操作的练习。 (1> implementations can feel free to browse introduce 任一景 points. (Function a) 2> You can give the shortest distance and route between any two attractions. (Function b) 3> You can view Renyi Jing point heat, and heat can all attractions (visits) to be sorted. (Function c) 4> each spot related content file reading, to achieve the file operations exercises.)

用分治算法（O(nlogn)复杂度）实现寻找n个点中最邻近点对,输出为最邻近距离的平方(Looking for n points nearest point, the output of the nearest neighbor distance squared using the divide-and-conquer algorithm (O (nlogn) complexity))

这个程序用来解决树结构与树之间的程序匹配的问题这个程序可以解决很多的问题(it is very good)

用c++实现的haffman tree 小程序，仅供参考 。 (The the haffman tree applet realized with c++ for reference only.)

用控制台实现了经典的数据结构B树，可以通过测试文件.txt加载已有的B树，有插入，删除，查找的功能，加深对数据结构的理解。(Using the console to achieve the classic B tree data structure, you can pass the test document. Txt already loaded B-tree, there are insert, delete, search functions, to deepen understanding of the data structure.)
