哈夫曼树的构建，源码实现，可用于排序等功能的实现-the implement of Huffman

在从键盘上输入字符时，只要是键盘上的字符任何字符都能接受，并能统计出输入的一串字符串中各个字符出现的次数，作为构建哈夫曼树时的各叶子结点的权值。 本程序同时具有译码功能 -Character input from the keyboard, as long as any of the characters in the character on the keyboard can be accepted, and the statistics of the number of occurr

实现霍夫曼编码和霍夫曼解码，并统计原文件中的各个字符出现的频率，将字符及其出现的频率保存至txt文件中，构建的霍夫曼树也将被保存至txt文件中。-Achieve Huffman coding and Huffman decoding and statistical frequency of each character in the original document that appears to save the characters and their frequency of occur

利用得到的权值构建huffman树、并输出每个字符对应的huffman编码，另外动态演示该哈夫曼树的生成过程。-Right to use the output value to construct the Huffman tree, and each character corresponding Huffman encoding, and dynamic display the generation process of the Huffman tree .
