    呃,就是用赫夫曼算法写的压缩解压程序。非常粗糙,只能压缩英文文章。因为里面的字符概率是基于自然语言的,源代码之类的没法压缩。而且会抛弃最后几个字母,嘿嘿。为了交作业,没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)
