hash

数据结构的课程设计，做的是一个交通查询，主要用到图的算法，和大家共享，欢迎指正！(Data structure curriculum design, do a query traffic, mainly used graph algorithms, and share, please correct me!)

二叉树的先序遍历。采用递归实现。释放资源时用了后序遍历。(Preorder traversal of a binary tree. Recursive implementation. Release resources used after preorder.)

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)

纯C语言写的小型通用数据库，一个C数据结构组科技小组的作品，附有开发思路PPT，这可是一个宝贵的资源哦，更底层的东西，运行于DOS提示符，可以新建数据库等操作。C的编程高手们值得参考一下。 (Pure C language to write a small general-purpose database, a data structure C Group Technology Group works to develop ideas with PPT, this is a valuable resource Oh, and the bottom of things, running on the DOS prompt, you can operate a new database. C programming masters worthy of reference.)

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)

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

这是一个简单的银行模拟系统 1、 客户的到达时间随机 2、 客户需要处理的业务随机（不同业务处理的平均长度不同，例如：取款时间较短，开户和销户时间较长） 3、 处理客户业务所需时间随机（在一定范围内） 4、 使用文本文件记录每个客户到达时间、业务处理时间、业务结束时间 5、 动态显示（刷新时间可调）目前每个窗口累计处理客户数量、等待人数，每个窗口的平均业务处理时间，不同业务类型业务的累计办理量。 (This is a simple bank simulation system 1 customer arrival time random 2, customers need to deal with the business of random (the average length of the different business processes, such as: the withdrawal shorter, longer to open an account and cancel the account) 3, the time required to deal with customer service random (within certain limits) 4, using a text file to record each customer arrival time, business processing time, the business end of time 5 dynamically display (refresh time is adjustable) each window is accumulated to handle the number of customers waiting for the number the average business processing time of each window, different type of business operations total for the amount.)

哈夫曼编码程序，实现计算编码学中哈夫曼编码程序的源代码。(Huffman coding procedures, the realization of computing science Huffman encoding procedure s source code.)

说明：  标准答案习题1 1.1 简述C++语言程序的结构特点。 答： （1）C++程序由一个或多个函数组成，其中至少有一个主函数main()，程序从主函数开始执行，由主函数来调用其他函数。(Standard answer to Exercise 11.1 on C++ Language program structural characteristics. Answer: (1) C++ Procedures by one or more functions, of which at least one of the main function main (), the procedure started from the main function, from the main function to call the other function.)

邻接表存储图，然后进行深度优先遍历及广度优先遍历。(DFS,adjacent matrix)
