利用栈完成算术表达式求值：从键盘或文件中输入算术表达式，计算其结果并显示。要求处理过程为：（1）转换为后缀表达式并输出；（2）对后缀表达式求值并输出。 输入的表达式中可以有整数、实数、括号，运算符包括+、-、*、/、#（代表单目负）。可以多次输入不同的表达式进行计算，直到用户选择“退出”。栈的基本操作可以自己实现，也可以使用系统提供的STL实现。 (Done using an arithmetic expression evaluation stack: file input from the keyboard or an arithmetic expression, calculate and display the results. Requirements process: (1) to postfix expression and output (2) evaluation of the postfix expression and output. Enter the expression can be integers, real numbers, parentheses, operators including+,-,*,/,#( representatives unary minus). You can enter several different expressions are evaluated until the user selects " Exit." Stack can implement the basic operations, you can also use the system implementation of the STL.)

该程序是数据结构中以链表存储形式来求两个集合的交集，用C++语言描述的(The program is the form of a linked list stored in the data structures to seek the intersection of two sets, C++ language to describe)

c语言完成的数据结构几个小算法游戏包括迷宫求解等(C language of complete data structure several small algorithm game includes maze solution, etc )

迷宫算法，1代表可以通过，0代表墙壁，自动找寻路线(Maze algorithm, 1 can pass 0 for the walls, automatically find routes)

kd-树（k维搜索树）是把二叉搜索树推广到多维数据的一种主存数据结构。这里给出了其代码的VC++实现(Classic data structures- KD tree full implementation, with a detailed explanation of the code, the novice data structure good materials)

VC简易通讯录，加强C的编程，熟悉链表文件的使用等。(Simple VC contacts, strengthen C programming, familiar with the use of a linked list file.)

数据结构：抽象数据类型的介绍；讲述如何构造函数和如何实现；(Data structure: the introduction of abstract data types on how to structure function and how to achieve )

使用不同的方法解决背包问题：本算法采用的是动态规划方法，比较好的解决背包问题。(Use different methods to solve knapsack problem: The algorithm is a dynamic programming approach, a better solution to knapsack problem.)

大二时做的一个数据结构的课程设计，用2-3树实现的图书馆管理系统，只是控制台程序，没有很好的图形界面。包括管理员、读者。管理员功能有：采编入库、查看图书、查看读者、删除读者。读者功能有：借书、还书、预约、查找等等。。功能全面。包括注册账号，登录需要账号密码。(Sophomore to do a data structure of the curriculum design, with 2-3 tree implementation of library management system, but the console program, not a good graphical interface. Including administrators, readers. Administrator functions include: editing storage, check books, check readers, delete readers. Reader functions: library, book, booking, search and so on. . Full-featured. Including the registration account, login account password required. )

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)
