哈夫曼树及哈夫曼编码，经过测试可用的，快来下载啊！-Huffman trees and Huffman coding, tested available, Come download ah!

哈夫曼树算法 根据给定的n个权值{w1,w2,……wn}，构造n棵只有根结点的二叉树，令起权值为wj 在森林中选取两棵根结点权值最小的树作左右子树，构造一棵新的二叉树，置新二叉树根结点权值为其左右子树根结点权值之和 在森林中删除这两棵树，同时将新得到的二叉树加入森林中 重复上述两步，直到只含一棵树为止，这棵树即哈夫曼树 -Huffman tree algorithm based on a given n-weights (w1, w2, ... ... wn), construct n trees only a root node of the tree, so that from the right value of wj in the forest root node to select two the right tree for the value of the smallest subtree around, a new binary tree structure, the right to buy a new tree root node value of its subtree root node around the right value in the forest and delete these two trees, At the same time, the new binary tree obtained by adding the forest to repeat the above two steps until a tree containing only the date, that is, Huffman tree tree

这是一则无刷新发帖的实例，也是对Ajax的一个实际应用，后台是Apache+PHP,数据是文本(之所以考虑文本方便，数据库的话还要先安装，反而搞的复杂，所以采用文本。当然了，实际应用当中是采用MySql还是文本可以另选)-This is a refreshing post had no examples of Ajax is also a practical application, the background is a Apache+ PHP, the data is text (the text is having convenient, if the database should be installed, but are engaged in complicated, so use a text . Of course, the practical application of which is used MySql or text can elect)
