一、 地理数据文件应用 对由点、线、面构成的地理数据文件进行打开、读取、关闭操作。 要求： 1、在C++环境下，通过程序设计实现文本格式数据文件的操作； 2、在打开数据文件后，生成点、线、面三个链表，分别用于记录三种类型的数据。 3、数据文件结构说明 (Geographic data file applications by point, line, surface consisting of geographic data file open, read, and close operations. Requirements: in C++ environment, through the program design text format data file operations 2, open the data file, generate points, lines, surfaces three linked list, respectively, for the record three types of data. 3, a data file structure)

说明：  根据所选定的字符顺序，按照从大到小的规则，对字符进行插入排序，(Insert and sort characters)

系统用srand()函数产生一个以当前时间开始的随机种子。其产生的种子用选择排序、冒泡排序、快速排序将顺序表中的数字排好，设置变量记录每种排序关键字的移动次数和关键字的比较次数。选择排序：利用L.length-1个循环，将随机种子按从小到大的顺序排好。(System with srand () function generates a random seed to start the current time. Which produces seeds with selection sort, bubble sort, quick sort the order of numbers in the table lined up, set the variable record number of comparisons for each mobile number and keyword sort key. Sort: use L.length-1 cycle, the random seed small to large order lined up. )

哈希表 数据结构课程设计 1.1问题描述 针对自己的班集体中的“人名”设计一个哈希表，使得平均查找长度不超过R，完成相应的建表和查表程序。 1.2基本要求 假设人名为中国姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。构造哈希函数，用链表法处理冲突。 1.3测试数据 读取熟悉的30个人的姓名作测试。(Hash table Data Structure Course Design 1.1 Description of the problem For their own class group of the "names" to design a hash table, making the average search length does not exceed R, the completion of construction of tables and look-up table corresponding procedures. 1.2 Basic requirements Assuming the name of the person called Chinese pinyin form. To be filled into a hash table names a total of 30, taking the average search length of the upper limit of 2. Construct a hash function, treatment with a list of conflict. 1.3 Test Data Read the familiar names of 30 individuals tested.)

最优二叉搜索树问题具有最优子结构性质，即其任意一棵子树都是一棵独立的最优二叉搜索树，所以可以采用动态规划方法，并且在每次更新时保存子树的根。(Optimal binary search tree problem has optimal substructure property that any of its sub-tree are an independent optimal binary search tree, so you can use dynamic programming methods, and save each update subtree roots.)
