Description: 动态演示各种数据结构的定义和操作:
实现过程:
建立一棵二叉树，并在所建立的二叉树中可在任意结点位置插入其左右孩子。
画出你所建的这棵二叉树，并能动态反映你所插结点的过程（具有可视化，彩色，美观的效果）
能查找任一结点的左右孩子
能查找任一结点的左右邻兄弟
能查找任一结点的父亲
能删除任一结点
能对树进行各种遍历-Dynamic demonstration of the definition of various data structures and operations: the realization of the process: the establishment of a binary tree and binary tree created can be in any position to insert node about its children. Draw your tree built binary tree, and you can dynamically reflect the process of interpolation nodes (with a visualization, color, aesthetic effects) can search any one node around children can search for any node o brothers around the search term can be the father of one node can delete any node can conduct various kinds of tree traversal

Description: 赫夫曼编译码器：
用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统对待传数据预先编码，在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双向传输信息的信道），每端都需要一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼码的编/译码系统。
[基本要求]一个完整的系统应具有以下功能：
（1）I：初始化（Initialization）。从终端读入字符集大小n，以及n个字符和n个权值，建立哈夫曼树，并将它存于文件hfmTree中。
（2）E：编码（Encoding）。利用已建好的哈夫曼树（如不在内存，则从文件hfmTree中读入），对文件ToBeTran中的正文进行编码，然后将结果存入文件CodeFile中。
（3）D：译码（Decoding）。利用已建好的哈夫曼树将文件CodeFile中的代码进行译码，结果存入文件TextFile中。
（4）P：印代码文件（Print）。将文件CodeFile以紧凑格式显示在终端上，每行50个代码。同时将此字符形式的编码文件写入文件CodePrin中。
（5）T：印哈夫曼树（Tree printing）。将已在内存中的哈夫曼树以直观的方式（树或凹入表形式）显示出，同时将此字符形式的哈夫曼树写入文件TreePrint中。

Description: C4.5算法有如下优点：产生的分类规则易于理解，准确率较高。其缺点是：在构造树的过程中，需要对数据集进行多次的顺序扫描和排序，因而导致算法的低效。此外，C4.5只适合于能够驻留于内存的数据集，当训练集大得无法在内存容纳时程序无法运行。-C4.5 algorithm has the following advantages: the classification rules easier to understand, accurate and a higher rate. Its shortcomings are as follows: in the tree structure, the need for a number of data sets the order of scanning and sorting, thus leading to inefficient algorithms. In addition, C4.5 can only be applied to the presence of a data set in memory, when the training set too great to accommodate in memory when the program can not run.
