Huffman

使用vc编写的一个动态链接库，测试动态链接库的例程(Vc prepared using a dynamic link library, dynamic link library routine testing)

数据结构 二叉树的操作，可以对二叉树进行最基本的操作，先建立二叉树。(The operation of the binary tree, binary tree with the most basic operation, first create a binary tree.)

数据结构线性表教学笔记，内容讲基础知识，没基础可以看看(Linear table data structure teaching notes, basic knowledge content says, no base can take a look)

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：  贪婪算法的简单描述 不过没做完 只是想下个程序 用用。。。。 (greed math)

Dijlstra算法 对任意图，选择合适的数据结构表示图，在此基础上实现求解最短路径的Dijkstra算法(Dijlstra algorithm to arbitrary map, select the appropriate data structures that map, on this basis to achieve solution of the Dijkstra shortest path algorithm)

说明：  分别用堆栈和数组的方法实现任何进制的数制转换(Arrays were used to stack and method of implementation of any binary number system conversion )

设计一个表达式求值的程序。该程序必须可以接受包含（，），+，-，*，/的中缀表达式，并求出结果。如果表达式正确，则输出表达式的结果；如果表达式非法，则不输出或输出其他字符。(Design an expression evaluation procedures. The program must accept (,), including +, -, *, / the infix expression, and the results obtained. If the expression is correct, the output of the expression is output; if the expression is illegal, no other characters are output or exported.)

百鸡算法是一种简单的逻辑算法，通过不同的鸡不同的价钱，得出大鸡小鸡的个数(Typical code for white chicken algorithm)

用c++实现的haffman tree 小程序，仅供参考 。 (The the haffman tree applet realized with c++ for reference only.)
