Description: 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对待传数据预先编码，在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双向传输信息的信道），每端都需要一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼码的编译码系统
基本要求：
1.接收原始数据：从终端读入字符集大小n,n个字符和n个权值，建立哈夫曼树
2.编码：利用已建好的哈夫曼树，对文件中的正文进行编码
3.译码：利用已建好的哈夫曼树将代码进行译码.

This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
