简单LR语法分析程序自动生成器的实现，可用作数据结构课程设计(LR (0) grammar analysis)

这是BFS算法的实现。用C语言实现的。好好学习吧。(This is achieved BFS algorithm. Implemented using C language. Learn it.)

数据结构二叉树，及其遍历，镜像，输出等相关操作C++源码。(Binary tree data structure and its traversal, mirror, output the operation C++ source.)

多项式加减乘 用数据节够得算法实现多项式的加减乘 原理简单易懂(suoxiangshi jiajiancheng)

C语言树的简单实现,介绍了树你前序遍历，树插入与删除节点的实现(C-tree is simple to achieve, before you introduced the tree traversal, tree insert and delete nodes to achieve)

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.)

自己编写的几种经典的排序算法，里面有自己做的PPT详细讲解，希望有帮助吧(I have written several classic sorting algorithm, which own PPT explain in detail, I hope to help!)

常用的算法经典代码，包括快速排序，冒泡排序等各种排序方法，还有二叉树的前序、中序和后序遍历等(The classic algorithm code, including quick sort and bubble sort sorting methods, as well as the preamble of the binary tree, inorder and postorder traversal, etc.)

使用的排序算法，非常不错的思维，比较其他有较大优势(Sorting algorithm used, very good ideas, have greater advantages compared with other)

说明：  任意给定输入的一个小写英文字符串a1a2a3…an-1an (n≥5) 输出：字符串Ana1An-1a2An-2a3…A2an-1A1an,其中Ai为ai的大写形式 例如，输入aybdx，则递归程序输出XaDyBbYdAx (Any given input of a lowercase string a1a2a3 ... an-1an (n ≥ 5) Output: the string Ana1An-1a2An-2a3 A2an-1A1an, which Ai ai uppercase for example, input aybdx recursive program output XaDyBbYdAx)
