说明：   利用哈夫曼编码进行住处通讯可以大大提高信道利用率,缩短住处传输时间,降低成本,但是,这要求在发送端通过一个编码系统将传输的数据预先编码,在接收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信道,每端都一个完整的编码译码系统,试为这样的住处收发站写一个哈夫曼友的编码译码系统.
(Residence using Huffman coding can greatly improve the communication channel utilization, reduce transmission time residence, reduce costs, but this requires the sending end through a coding system to transmit the data pre-encoding, decoding at the receiving end system through a decoding the data transmitted (recovery), for two-way transmission of information channels, each side is a complete encoding and decoding system, test for such accommodation hubs Friends Write a Huffman coding and decoding system.)
