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)

说明：  链表逆转,实现单链表的逆转程序，数据结构(List Inverse)

使用三叉链表实现的哈夫曼树,统计inputfile1.txt中各字符的出现频率，并据此构造Huffman树，编制Huffman 码；根据已经得到的编码，对01形式的编码段进行译码。 具体的要求： 1．将给定字符文件编码，生成编码，输出每个字符出现的次数和编码； 2．将给定编码文件译码，生成字符，输出编码及其对应字符。 (Emergence of the frequency of each character in the trigeminal lists using the Huffman tree, statistics inputfile1.txt, and accordingly the Huffman tree structure, preparation of Huffman code according to the coding has been. 01 to form the code segment for decoding. Specific requirements: 1 coding the given character file, generating the encoding, and outputting the number and encoding of each character 2 will be given the encoding file decoding, generating the character, the output code and its corresponding character.)

效验算法单循环链表，这些都是实用经典的算法和数据结构(Well-tested algorithm round robin list, these are practical classic algorithms and data structures)

说明：  详细介绍了游戏设计的数据结构注意事项，对与游戏中角色和游戏模式作者给予了督导的见解，书中语言为全英文但通俗易懂！很是推荐 (Data.Structures.For.Game.Programmers Detailed data structure of the game design considerations, the role with the game and game modes of supervision given to insights, the book in English but the language is easy to understand! It is recommended)

校园导航系统包含佛山科技学院本部校区的校园景点平面图。通过系统的各功能不仅可以查询任意景点的编号，名称，简介等信息，还可以查询任意两景点间的最短路径及长度和所有路径及长度。另外，还可以通过一系列操作增加，更改或删除任意的景点的各信息。(Contains the campus attractions plan of the campus Foshan Institute of Technology campus navigation system. Through the function of the system not only can query any spots number, name, profile and other information, can also query the shortest path and arbitrary length between two spots and all paths and the length of. In addition, can also increase through a series of operations, the information change or delete any of the attractions.)

数据结构中的一元多项式相加，多于考研算法实现很重要。后续部分将在后期上传！(The sum of Multinomial)

迷宫问题 队列求解 界面还不完善 可以自己添加(Maze problem solving interface queue is not perfect you can add your own)

利用佛洛伊德算法计算节点之间的最短路径,用于复杂网络中计算平均路径长度(average path lengh)
