    首先通过文件操作,读取文件内容,把字符逐个提取后统计字符频率,建立哈夫曼树和进行哈夫曼编码,当然这是根据ASCII编码来将字符转换为二进制,然后实现前缀编码,然后把编码后的使用二进制流写入相应文件(First through file operations, read the file content, the characters one by one after extracting character frequency statistics, establish a Huffman tree and Huffman encoding, and, of course, this is according to ASCII code to convert characters to the binary, then realize the prefix encoding, and then the encoded using binary stream into the corresponding files )

    可以实现CSV的写入文件读取。同样如果将程序稍作改动就可实现各种格式的文件的写入和读取。文件是以逗号和回车为间隔的写入的。这样可以用excel软件打开该文件。同时,在读取时,将存取的数字在逗号和回车的交替中提取出来。(You can write the CSV file to read.

The same time, in reading, access to digital in the alternation of comma and carriage return is extracted. )
