匈牙利算法以及指派问题介绍，kM算法和匈牙利算法的程序代码(Hungarian algorithm and the assignment problem introduced, kM algorithm and the Hungarian algorithm code)

说明：  用链表的方式实现多项式的加减，其中结构体包含幂次和系数。(Polynomial addition and subtraction with a list of ways in which the structure and contains the power of coefficients.)

数据挖掘中聚类算发中基于密度的算法DBSCAN(Hair count data mining clustering algorithm DBSCAN density-based)

这是BFS算法的实现。用C语言实现的。好好学习吧。(This is achieved BFS algorithm. Implemented using C language. Learn it.)

先序创建二叉树，将二叉树所有节点的左右子树交换，再先序遍历输出(create a binary tree in first order, exchange all the nodes of the binary subtree , then preorder output)

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

说明：  从最后一个非叶子结点开始从后往前进行调整，保证了根下的所有子树都是最大堆，最后对根进行调整，使整棵二叉树为最大堆，保证了根结点为整棵数的最大值点，完成了建堆的过程，再将根结点跟最后一个结点进行交换，如此反复操作，则堆排序就完成了，其中堆排序的过程采用了满二叉树的概念。(From the final of a non-leaf node after the move began to be adjusted to ensure that the root of all sub-tree are the biggest pile, and finally adjusted to the root, so that the largest heap binary tree整棵to ensure that the root node for整棵the maximum number of points, completed the process of building reactors, and then the last root node with a node to be exchanged, and so repeated the operation, then HEAPSORT completed, of which the process of HEAPSORT a full binary tree concept.)

说明：  给定程序中，函数fun的功能是：将a所指3×5矩阵中第k列的元素左移到第0列，第k列以后的每列元素依次左移，原来左边的各列依次绕道右边。 例如，有以下矩阵： 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 若k结果为2，程序执行结果为： 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 请在程序的下划线处填入正确的内容并把下划线删除，使程序得出正确的结果。 注意：源文件存放在考生文件夹下的BLANK1.C中 不得增行或删行，也不得更改程序的结构！ (A given program, function fun feature is: a 3 × 5 matrix referred to in the first k elements of the left column to move Section 0, the k elements of each column after column followed by the left, the original columns in the left turn Bypass on the right. For example, the following matrix: 123,451,234,512,345 If k is 2, the program execution results: 345,123,451,234,512 in the program underscore the right content at the fill and to remove the underscore, so that the program reach the right result. Note: The source files in the folder of BLANK1.C candidates are not allowed by the line or delete line, nor change the structure of the program!)

有理数的算法，包括其加减乘除，启用的是单链表的形式来表达(Rational algorithms, including addition, subtraction, enabling a single-chain form of expression)
