二叉树的各种遍历。递归和非递归遍历以及层次遍历。-the binary tree traversal. And recursive and non- recursive traversal level traverse.

（１） 用一个４＊２０的二维数组Ｍ，第１行存放按从小到大排序的20个所给出的ai和bi，第２行存放相应的作业序号，第３行存放１或２(１代表是来自ai，２代表是来自bi), 第4行存放0或１（０代表作业序号未进入最优调度方案；１代表作业序号已进入最优调度方案） （２） 排序完后，按课本所述方法求一种最优调度方案，存放在S中。 -(1) with a 4* 20 two-dimensional array M, the first a line to deposit a small to large order of 20 given by ai and bi, line 2 store operation corresponding serial number, the first three lines deposited one or 2 (a representative from the ai, 2 representatives from the bi), the first four rows stored 0 or 1 (0 for job number to gain access to optimal scheduling programs a job number has been entered on behalf of the optimal scheduling scheme) ( 2) Sort exhausted, according to the methods described in textbooks, seeking the optimal scheduling of a program stored in the S in.

数据结构里的拓扑排序和非拓扑排序算法，用vc6.0编写-data structure, the topological sorting and topological sorting algorithm used to prepare vc6.0

利用mfc和opengl编译的圆的绘制代码，里面有两个主要是利用扫描射线和多边形接近法

实现哈夫曼编码译码，可以实现，本实验可以实现编码，译码，打印哈夫曼数，等-There is a chance to appreciate different ways of life.

一种基于数据访问流的数据库索引优化方法该方法通过集成业务流程模型与数据模型，抽取了流程活动中包含的数据访问操作和流程的控制结构形成数据访问流，分析了数据访问流中数据访问操作的频度，为频繁数据访问操作所对应的数据项创建索引，达到改善数据访问性能的目的。实验结果表明，该方法提高了数据查询的速度。-A novel method called data-access-flow based index optimization (DAFIO) is proposed to provide automatic index select for databasein order to improve the data access performance. By integrating the data model and process model of the IT systems and getting data access flow, theDAFIO method can analyze the data access flow to find those data item which are accessed frequently, and then create indexes for these frequentitems. The experiment results show that the novel method is effective to improve the data access performance.

这个程序使用递归解决汉诺塔游戏的问题。 这个程序将所有盘从嘴左边的指针处移动到最右边，并满足以下要求1) 一次仅移动一个盘子.2)移除的盘子必须放到一个指针下面 3)大盘子不能放在小盘子上面
