数据结构 二叉树的操作，可以对二叉树进行最基本的操作，先建立二叉树。(The operation of the binary tree, binary tree with the most basic operation, first create a binary tree.)

简单选择排序，这是个解决排序问题的一个算法模型之一。(Sort simple choice, this is a solution to a scheduling problem, one algorithm model.)

说明：  由C程序实现的 数学上 滑雪问题 的代码实现，供大家学习用(Ski problem code for all to learn to use)

用c/c++写的二叉排序树的插入与删除，有兴趣的朋友可以看一下(Insertions and deletions using c/c++ to write binary sort tree)

说明：  一个实现外部排序的程序，其中gnerate.cpp为产生一个随机的文件，用于被排序。而caculate.cpp为外部排序程序。(A realization of the external sort program, which gnerate.cpp to generate a random file for be sorted. The caculate.cpp external sort program.)

纯C语言编程的模拟现有图书馆的借阅、续借、归还；图书入库、出库；查询、排序等功能，实现电子图书馆的智慧综合管理。其中查询功能里面嵌套精确查询，排序功能有六种，界面可变色，里面已经附带50多本图书信息包括图书摘要等详细信息。里面还附带详细设计报告和解说PPt。(Pure C language programming simulation existing library borrow, renew, return book storage, a library queries, sorting and other functions, to achieve integrated management of electronic library wisdom. Precisely where the query function inside a nested query, sort function has six, the interface can change color, which has included more than 50 books including books summary information and other details. Which also included detailed design reports and commentary PPt.)

自己做的一个用用栈实现类的操作，是课内作业，希望和大家互相交流(Own a type used by the realization of the operation of the stack is class work, hope and we can exchange ideas)

已知二叉树的先序遍历结果，建立二叉树并输出其先序、中序、后序遍历结果(Build a binary tree and print the results of preorder, midorder and postorder traversals based on the known result of preorder traversal)

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)

参加运动会的 个学校编号为 。比赛分成 个男子项目和 个女子项目，项目编号分别为 和 。由于各项目参加人数差别较大，有些项目取前五名，得分顺序为7，5，3，2，1；还有些项目只取前三名，得分顺序为5，3，2。写一个统计程序产生各种成绩单和得分报表。 2、要求产生各学校的成绩单，内容包括各校所取得的每项成绩的项目号、名次（成绩）、姓名和得分；产生团体总分报表，内容包括校号、男子团体总分、女子团体总分和团体总分。 3、测试数据：对于 ， ， ，编号为奇数的项目取前五名，编号为偶数的项目取前三名，设计一组实例数据。 (The school serial number participating in Games is. Competition divides into men s event and women s event , the project serial number parts for the sum. The difference is bigger since every project participates in a number , some projects choose the first five , score order is 7 , 5 , 3 , 2 , 1 Still have some of projects taking the first three places , score only being 5 , 3 , 2 in proper order. Write a form for report counting procedure producing the various school report card and score. 2, demands the school report card producing every school , content includes every achievement project number , position in a name list (achievement) , full name and score per got by school Produce the group total points form for report , content including the school number , male person group total points , woman group total points and group total points. 3, testing data: Be that the odd number project chooses the first five to the serial number, the serial number is that the even number project c)
