该文件描述了排序算法的实验指导报告，通过本实验，你可以了解插入排序、选择排序、希尔排序、堆排序、冒泡、双向冒泡、快速排序、归并排序、递归的归并排序、基数排序等多种排序方法的实验(The document describes the experimental guidance of the sorting algorithm, through this experiment, you can learn about the insertion sort, selection sort, shell sort, heap sort, bubble, two-way bubble, quick sort, merge sort, merge sort recursive basesorting a variety of sorting methods experiment )

① 实现在B-树上的查找，并分析其时间复杂性。 ② 实现B-树的ADT，包括其上的基本操作：结点的加入和删除。 ③ 要求B-树结构中的M=3 或5，实现其中的一种即可。 ④ 实现基本操作的演示。 (4) 实现提示 (b-trees c/c++)

校园导航系统 1） 校园景点介：绍介相关景点的有关详细信息。 2） 最佳路线查询：查询校园中任意两点之间所有路线，并提供两点间最短的简单路径。 3） 关节点查询：提供校园图的关节点查询。 4） 多景点最佳路线查询：提供多个景点的最佳线路查询，即求途径这个景点的最佳路径。 (Campus Navigation System 1) campus attractions Introduction: Shao Jie-related attractions for more information. 2) The best route query: Query on campus all the routes between any two points, and provides a simple shortest path between two points. 3) joint points: the key points to provide the campus map queries. 4) The best route queries more attractions: multiple sites to provide the best route queries, that is seeking ways to this spot the best path.)

Polynomial基于数据结构的思想,文件比较小,可以直接运行(Polynomial based on the idea of ​ ​ data structures, file is relatively small and can be run directly)

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)

设有一头指针为L的带有表头结点的非循环双向链表，其每个结点中除有prev（前驱指针），data（数据）和next（后继指针）域外，还有一个访问频度域freq。在链表被起用前，其值均初始化为零。每当在链表中进行一次Locate(L,x)运算时，令元素值为x的结点中freq域的值增1，并使此链表中结点保持按访问频度非增（递减）的顺序排列，同时最近访问的结点排在频度相同的结点的最后，以便使频繁访问的结点总是靠近表头。试编写符合上述要求的Locate(L,x)运算的算法，该运算为函数过程，返回找到结点的地址，类型为指针型。(Has a head pointer is non-circular doubly linked list L with a header node, each node in addition to prev (precursor pointer), data (data) and next (successor pointers) outside, there is an access frequency degree domain freq. Before the list was hired, their values are initialized to zero. Whenever carried out in the list once Locate (L, x) when the operation, so that the element node x is the value in freq domain by one, and keep this list in the node-access frequency of non-increasing (decreasing) the order, while a recent visit to the nodes in the same row of the frequency of the last node, so that the nodes are frequently accessed tables are always near the head. Locate (L, x) algorithm is prepared in accordance with the above requirements of the test operation, the operation as a function of the process, return to find the address of the node of type pointer.)
