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. )

这是一个二叉树左右子树交换的简单程序，希望对大家有用！(This is a binary tree so the simple sub-tree exchange procedures in the hope for all of us!)

基于MFC平台，实现多功能计算器，可求解复杂表达式，主要实现为数据结构中链表和数组，对于要熟悉链表和数组的初学者有很帮助。(Based on the MFC platform, to achieve multi-function calculator, can solve complex expressions, the main realization of the data structure for the list and array, to be familiar with the list and the array of beginners helpful.)

说明：  二叉树的演示程序。实现了二叉树和哈弗曼树(Binary tree demo program. Implements a binary tree and the tree Hafu Man)

数据结构，利用霍夫曼树实现文本数据的压缩。(Huffman data compression and decompression.)

实现经典问题老鼠迷宫，并用坐标将路径显示出来(Achieve classic problem rat maze, and coordinate with the path displayed)

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.)

输入俩条线段的首尾坐标，用于判断俩条线段是否相交的(Used to determine whether the intersection of two line segments)

使用VC编写的约瑟夫环程序，简单明了，方便使用(Prepared using the VC Joseph Central program, simple and clear, easy to use)

二叉树类的前序，后序，层次遍历，其以链表方式存储(Binary tree class pre-order, post-order, hierarchy traversal, the linked list storage)
