根据所选定的字符顺序，按照从大到小的规则，对字符进行插入排序，(Insert and sort characters)

二叉树的链式存储、先序中序遍历和层次遍历。（构造一棵树并输入数据，编写三个函数，非别是树的前序递归遍历算法、树的后序递归遍历算法、树的非递归中序遍历算法（这里的非递归以中序为例）。在主程序中调用这三个函数进行树的遍历，观察用不同的遍历方法输出的数据的顺序和验证递归与非递归输出的数据是否一样。）(Chain store binary tree, preorder traversal and hierarchy traversal.)

读取数据，统计所得到的文件中每个字母的权值，创建哈夫曼树，哈夫曼编码。哈夫曼解码，解码后内容写入到指定的文件。 读取数据里面的内容是由英文单词组成。读取文件的时候传入文件存放的路径、读取方式以及读出以后存放的数组，最终可以得到一个存放目标文件内容的数组。 将得到的数组进行字母权值的统计，统计每个字母出现的次数，次数即为每个字母的权值。 将得到的字符数组与权值数组作为创建哈夫曼树的依据，哈夫曼树根据每个字母权值的大小来创建，每个节点，包括权值、父节点、左子、右子和字母本身。 根据哈夫曼树进行编码。形成目标文件的哈夫曼编码，将此编码返回。 根据哈夫曼树得到的数组即为解码数组，解码数组作为解码的结果返回。 写入输出文件，将解码得到的数组、文件的完整路径以及文件的写方式作为参数传入，将数组写入到相应的文件中。 (Read the data, statistical documents obtained weights for each letter, create a Huffman tree, Huffman coding. Huffman decoding, the decoded contents are written to the specified file. Read the content inside is composed of English words. When the incoming file to read the file storage path, read mode and read out after storage array that can eventually get a storage target file contents of the array. The resulting array of letter weights statistics, statistical number of occurrences of each letter, the number is the weight of each letter. The resulting character array with the weights array as the basis for creating Huffman tree, Huffman tree based on the size of the weights of each letter to create, for each node, including weights, parent, left child, right child, and letter itself. According to Huffman coding. The formation of the target file Huffman coding, this code returns. According to Huffman decoding the resulting array is an array, the decoder decodes the result is retur)

说明：  一个用VS2008编写的冒泡排序算法演示程序，数组都是随机生成的。(Bubble Sort)

使用C语言完成党的霍夫曼编码，主要使用树的数据结构，作为巩固数据结构的练习(Using the C language to complete the party' s Huffman coding, the main use of the tree data structure, data structure as a consolidation exercise)

主要是DIJKSTRA经典算法，可以作为单个算法来读，也可以调用。(DIJKSTRA mainly classical algorithm can be read as a single algorithm can also be called.)

自己编写的floyd 最短距离求解程序。实用简单。gcc (Floyd shortest distance to write your own solver. Practical and simple. gcc)

各种排序算法的实现，如快速排序，冒泡排序，选择排序，堆排序，二分插入排序等(Implementation of various sorting algorithms, such as quick sort, bubble sort, selection sort, heap sort, binary insertion sort, etc.)

关于Arnoldi算法的今年来的中文资料，希望能够给有兴趣编写这方面算法的人提供帮助(Arnoldi algorithm on the Chinese data this year, hoping to write this algorithm are interested in helping people)

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)
