FreeTree

数据结构中的许多东西,包括头文件、例题、习题等等(Data structure many things, including the header files, examples, exercises, etc.)

主要用栈和树求解骑士问题，用C++语言编写的(The main stack and tree Cavalier Problem Solving with C++ languages)

关于二叉树的一些相关代码，运用链表的形式，求二叉树的高度，结点个数以及叶节点个数(Some of the relevant code on the binary tree, using a linked list, find the height of a binary tree, the number of nodes, and the number of leaf nodes)

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)

棋盘覆盖，算法分析，很有用的东西，大家一起来分享一下(Board covers, algorithm analysis, useful things, we share together)

这是我在学习数据结构做练习时写的一个小程序，功能是在命令行下进行形如：23+34*3/4+(3*6+10)的四则运算，支持+,-,*,/,(,)进行整数运算。(This is a simple code about data structure.It uses to carry on four arithmetic operations with parenthesis.But now it only supports integer.)

矩阵运算器，c语言编程，数据结构，免费下载(Matrix calculator, c language programming, data structures, free download)

电梯模拟，实现一个模拟电梯的环境，用C程序实现的，封装良好(elevator modify)

参加数学建模的同学很可能会遇到这套题。本程序采用链表进行编写，很方便地解决了小白鼠问题。(Mathematical modeling of the students participating are likely to encounter this question, the program uses the list to solve the problem of mice, very convenient.)

c语言的一些小李子，初学c的朋友有帮助，主要有顺序表、二分查找、二叉树、单链表等等(Some Survival Song c language, c beginner to help a friend, there are sequence tables, binary search, binary tree, a single linked list, etc.)
