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)

程序可以实现哈弗曼自动编码功能！很详细的！很有参考价值！(Program can be Havermann automatic coding features! Very detailed! A good reference!)

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)

说明：  用从c＋＋写的floyd最短路径算法，可以求邻接矩阵任意两点的最短路径。(from using c++ to write the Floyd shortest path algorithm, can help adjacency matrix arbitrary 2:00 Shortest Path.)

总结了10种排序的方式。用代码加以实现。(the ten way of Line up a preface)

说明：  进程死锁.资源分配图的绘制 建立所需数据结构；  使用题目21存成的资源分配图的文件作为输入；  编写资源分配图化简算法；  每化简一步，在屏幕上显示化简的当前结果；  最后给出结论，是否死锁，如思索给出死锁的进程及资源； (Process deadlock. Resource allocation mapping  establish the required data structures  Use title 21 deposit into resource allocation graph file as input  writing resource allocation map simplification algorithm  Each simplification step, on-screen display simplification of the current result  Finally, the conclusion of a deadlock, deadlock is given as thinking processes and resources )

c++用栈来实现迷宫求解（c语言数据结构）(c++ stack maze solving (c language data structure))

这是birch C语言的源代码。里面有详细的代码注释方便学习birch算法(birch c)

说明：  由C程序实现的 数学上 滑雪问题 的代码实现，供大家学习用(Ski problem code for all to learn to use)

根据队列搜索算法的基本思想，现设计了一个简单的结构体数组如下定义代码所示。此结构体数组具备控制结点搜索和存储结点信息和路径的功能，可以较好的实现TDN的最小时间路径搜索。(Search algorithm based on the basic idea of ​ ​ the queue is now designed a simple structure array as defined code. This structure array with the control node and storage node information search and path functions, you can achieve better TDN minimum time path search.)
