利用哈夫曼编码进行通信可以大大提高信道的利用率，缩短信息传输的时间，降低传输成本。根据哈夫曼编码的原理，编写一个程序，在用户输入结点权值的基础上求哈夫曼编码。-The use of Huffman coding to communicate can greatly improve channel utilization, shorten the time of information transmission, reducing transmission costs. Huffman coding in accordance with the principles of the preparation of a process node in the user input the right value based on the order Huffman coding.
