哈夫曼码的编码译码系统 问题描述 利用哈夫曼编码进行信息通讯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将待传输的数据预先编码：在接受端通过一个译码系统对传来的数据进行译码（复原）。对于双向传输信息的通道，每端都需要一个完整的编码译码系统。试为这样的信息收发站编写一个哈夫曼码的编码译码系统。-Huffman coding code decoding system describes the use of Huffman coding informa

来有人提出了一种动态的哈夫曼编码方法。动态哈夫曼编码使用一棵动态变化的哈夫曼树，对第t+1个字符的编码是根据原始数据中前t个字符得到的哈夫曼树来进行的，编码和解码使用相同的初始哈夫曼树，每处理完一个字符，编码和解码使用相同的方法修改哈夫曼树，所以-was raised to a dynamic Huffman coding method. Dynamic Huffman coding using a dynamic changes in the Huffman tree for the firs
