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)

This is a C++ code. It finds out if the tree is a binary search tree (BST)or not, where the BST is one of data structures types.

多段图、遍历、排序。用C语言解决多段图中的成本问题，得出最佳优化方案。(More paragraphs figure, traverse, ranking. C language solve more paragraphs in the chart the cost, obtains the best optimization scheme. )

用c/c++写的二叉排序树的插入与删除，有兴趣的朋友可以看一下(Insertions and deletions using c/c++ to write binary sort tree)

代码注重B树插入、删除的算法逻辑，适用于 学习者研究B树实现的核心思想。代码中无庞杂的无关操作(focus on B-tree code insertion, deletion algorithm logic applies to B-tree research learners to achieve the core idea. The code has nothing to do with the complex operation )

本代码主要实现了哈希表的设计，完成了哈希函数的相关要求。(The code is designed to achieve a hash table, the completion of the relevant requirements of the hash function.)

实验内容： 建立一个包含图书（书号，书名，定价）信息的的链表，并具有如下功能： (1) 根据指定图书个数，逐个输入图书信息； (2) 根据书名进行查找，返回此书的书号和定价； (3) 根据指定的位置可返回相应的图书信息（书号，书名，定价）； (4) 给定一个图书信息，插入到表中指定的位置； (5) 删除指定位置的图书记录； (6) 统计表中图书个数。 (It is a good c++.)

用不多于四种颜色为地图染色，使相邻的行政区不重色，是计算机科学中著名的“四染色”的典型应用，应用这个思想，是以回溯的算法对一幅给定的地图染色。是对数据结构中栈的应用。(With no more than four colors map staining the adjacent borough is not heavy color, typical applications of computer science "stain" the application of this idea, a backtracking algorithm on a given mapstaining. The application of the stack data structure.)

数据结构上机操作实验的实验1，线性表的基本操作！！！(the basic operation of sq of date structure)

二叉树的先序遍历。采用递归实现。释放资源时用了后序遍历。(Preorder traversal of a binary tree. Recursive implementation. Release resources used after preorder.)
