DBSCAN

通过冒泡排序法和选择排序法实现对若干数字的排序。(To achieve the order of several numbers)

说明：  可以实现判断二叉树是否为完全二叉树、判断两棵二叉树是否镜像对称、求一棵二叉树的一个最长枝等功能(Can determine whether the binary tree is complete binary tree to determine whether two binary mirror symmetry, one of the longest seeking a binary tree branches and other functions)

说明：  拓扑排序 　 对一个 有向无环图 G进行拓扑排序，是将G中所有顶点排成一个线性序列，使得图中任 意一对顶点u和v，若u，v ∈E，则u在线性序列中出现在v之前。 　 通常，这样的线性序列称为满足拓扑次序的序列，简称 拓扑序列 。 注意： 　 ①若将图中顶点按拓扑次序排成一行，则图中所有的有向边均是从左指向右的。 　 ②若图中存在有向环，则不可能使顶点满足拓扑次序。 　 ③一个DAG的拓扑序列通常表示某种方案切实可行。 (Topological sort In a directed acyclic graph G topological sort, is all vertices will G formed a linear sequence, make diagram post Meaning a pair of vertex u and v, if u, v ∈ E, then u in linear sequence in which they appear in v before. Usually, such linear sequence sequence of topological order called meet, abbreviation topology sequence. Note: (1) if the diagram according to the topology order line vertices, then figure all from left to right edge are pointing. (2) if the figure to exist in the ring, is impossible to have the vertex meet topological sequence. (3) a DAG topological sequence usually expressed some scheme is feasible. )

主要是DIJKSTRA经典算法，可以作为单个算法来读，也可以调用。(DIJKSTRA mainly classical algorithm can be read as a single algorithm can also be called.)

各种排序的模板实现，并分析了各种实现的时间复杂度及改进办法(Templates of various sort, and analyze the time complexity of the various implementations and ways to improve)

　广度优先搜索及深度优先搜索，用C语言实现，比较使用(Breadth-first search and depth first search, using C language, compared with)

具有数据插入、修改、删除、显示、和查询功能的电话簿管理程序。 数据包括：人名、工作单位、电话号码、和E-mail地址。 可对记录中的姓名和电话号码进行修改。 可增加或删除记录。 可显示所有保存的记录。 可按人名或电话号码进行查询。 附加功能： 可修改单个记录的各项内容。 可重新建立电话簿。 可按人名或号码进行排序。 可统计名片数目及可再添加数目。 可插入单个名片并不破坏原有顺序(With the data to insert, modify, delete, display, and query functions of the phone book management program. The data include: the names, work units, phone number, and E-mail address. Can be modified to record the name and phone number. Increase or delete records. You can display all the records kept. According to the names or telephone number for queries. Additional features: you can modify the content of a single record. Can re-establish a Phonebook. According to the names or numbers to be sorted. Statistical card number and add the number. Insert a single card does not destroy the original order)

KD树算法，能够实现对点云数据进行压缩，非常简单，适用于初学者(KD tree algorithm, can achieve the point cloud data compression, very simple, suitable for beginners)

一个苹果走迷宫，支持最短路径寻路。可以使用方向键操作，也可以用户自己添加迷宫格式文件，生成迷宫图。(Apple Maze, shortest path routing. Can use the arrow keys to operate, the user can add their own maze format generated maze.)

使用C语言完成党的霍夫曼编码，主要使用树的数据结构，作为巩固数据结构的练习(Using the C language to complete the party' s Huffman coding, the main use of the tree data structure, data structure as a consolidation exercise)
