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. )

实现了多项式的创建，实现了多项式的加减乘除等基本操作(The realization of polynomial create, to achieve the polynomial add, subtract, multiply and divide the basic operation)

利用串来比较数据大小，代码中有两个串，通过串来比较大小( 10/5000 Use the string to compare the data size)

思塞恩算法 常用算法之一 算法导论提及(strassen algorithm which can run correctly)

迷宫求解一般采用“穷举法”，逐一沿顺时针方向查找相邻块（一共四块－东(右)、南(下)，西(左)、北(上)）是否可通，即该相邻块既是通道块，且不在当前路径上。用一个栈来记录已走过的路径栈是限定仅在表尾(top)进行插入或删除操作的线性表。(Maze solving generally use the " exhaustive" one by one to find adjacent blocks in a clockwise direction (a total of four- East (right), South (down), West (left), North (on)) whether to pass, that the both channel blocks adjacent blocks, and not in the current path. Use a stack to record the path traversed stack is limited only in the tail (top) to insert or delete a linear form.)

floyd算法 数据结构 求最短路径(floyd algorithm for data structure for shortest path)

C语言树的简单实现,介绍了树你前序遍历，树插入与删除节点的实现(C-tree is simple to achieve, before you introduced the tree traversal, tree insert and delete nodes to achieve)

日历显示，查询1900年后的日历。每一屏显示一年的日历祥情。(Calender dispaling. Acess the calender detail of years after 1900.)

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!)

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)
