文件压缩/解压缩程序Huffman编码 数据结构实习

//哈夫曼树 最开始来自信号处理//一亿个数排序

【问题描述】

利用哈夫曼编码进行对已有文件进行重新编码可以大大提高减小文件大小,减少存储空间。但是,这要求在首先对一个现有文件进行编码行成新的文件,也就是压缩。在文件使用时,再对压缩文件进行解压缩,也就是译码,复原原有文件。试为完成此功能,写一个压缩/解压缩软件。

After seeing the movie Rise of the Planet of the Apes,I got many thoughts in my mind.These thoughts are so strange that I was shocked when it first come out.In my mind, I always thought human might live at the earth as a leader,and human might be the smartest race in the world for a long time.However,this movie tells me the possibility that sciences might lead.The another depression is that human ‘s morality sometimes went bad and some are originally bad.The Caesar,a ape human intelligence,was treated unfairly by a wicked man and developed a bad expression on human.

In my opinion,all races are equal.We all appeal for human’s equal rights but we never ask for other races right on the earth.It’s time we human reflect on ourselves.
