访客人数统计可以记录访问网站的人数，访客统计器通常放在网站首页，当有访问时候，就将数据库中人数字段自动加一。-Statistics on the number of visitors visit the site can record the number of visitors on the site statistics page normally, when there is access, the database will automatically add a number of fields.

与清华大学版的《数据结构》匹配二叉树的实现：BITREE1.CPP：为主程序，其中实现了递归算法以及非递归算法的前序遍历，中序遍历，后序遍历。TSTACK1.H: 为头文件，其中定义了一些常量的值，其中也包括了书中第三章的栈的实现，只需要将注解符去掉即可。运行环境为：VC++6 或 TC3-and Tsinghua University version of the "data structure" matching the achievement of a binary tree : BITREE1.CPP : mainly procedures, which achieved a recursive and non- recursive algorithm of algorithms preorder, preorder, after preorder. TSTACK1.H : for the first document, which defines a number of the value of a constant, which also include a third chapter of the book stack the realization simply have the website notes can be removed. Operating environment : VC 6 or TC3

假设一个文件中出现了8种符号S0，SQ，S2，S3，S4，S5，S6，S7，那么每种符号要编码，至少需要3bit。假设编码成000，001， 010，011，100，101，110，111。那么符号序列S0S1S7S0S1S6S2S2S3S4S5S0S0S1编码后变成 000001111000001110010010011100101000000001，共用了42bit。我们发现S0，S1，S2这3个符号出现的频率比较大，其它符号出现的频率比较小，我们采用这样的编码方案：S0到S7的码辽分别01，11，101，0000，0001，0010，0011， 100，那么上述符号序列变成011110001110011101101000000010010010111，共用了39bit。尽管有些码字如 S3，S4，S5，S6变长了(由3位变成4位)，但使用频繁的几个码字如S0，S1变短了，所以实现了压缩。对于上述的编码可能导致解码出现非单值性：比如说，如果S0的码字为01，S2的码字为011，那么当序列中出现011时，你不知道是S0的码字后面跟了个1，还是完整的一个S2的码字。因此，编码必须保证较短的编码决不能是较长编码的前缀。符合这种要求的编码称之为前缀编码。要构造符合这样的二进制编码体系，可以通过二叉树来实现。-Suppose a file appears in eight kinds of symbols S0, SQ, S2, S3, S4, S5, S6, S7, then each symbol to be encoded, at least 3bit. Suppose encoding 000,001, 010,011,100,101,110,111. Then the symbolic sequence S0S1S7S0S1S6S2S2S3S4S5S0S0S1 encoded into 000001111000001110010010011100101000000001, sharing a 42bit. We found that S0, S1, S2 these three symbols the frequency of relatively large, the other symbols the frequency is relatively smal

shi.c 说明:本程序用于层序遍历二叉树.程序开始时先由用户先根序输入二叉树各结点值,对于空结点输入宏ENDTAG所对的值(暂定为整数0). 建立好二叉树后即可自动进行遍历依次层序输出各结点的值. ----Author:zhg 2006.11.26 E-mail: wudazhg@163.com 仅供参考学习之用，所有权保留-shi.c : The procedures for the binary tree traversal sequence. procedures at the beginning of each user input first-sequence binary tree nodes value, for the importation of empty node by right-ENDTAG value (tentatively scheduled for integer 0).
