哈夫曼编码译码系统，设置发送者和接受者两个功能，

发送者的功能包括：

①输入待传送的字符信息；

②统计字符信息中出现的字符种类数和各字符出现的次数（频率）；

②根据字符的种类数和各自出现的次数建立哈夫曼树；

③利用以上哈夫曼树求出各字符的哈夫曼编码；

④将字符信息转换成对应的编码信息进行传送。

接受者的功能包括：

①接收发送者传送来的编码信息；

②利用上述哈夫曼树对编码信息进行翻译，即将编码信息还原成发送前的字符信息。

-Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information　② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree)　② According to the number of types of characters and their respective number of occurrences　③ use the Huffman tree to find the characters Huffman coding　④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission　② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.
