摘要： 哈夫曼编码简介（转）2010年03月17日|本网站遵守CC版权协议转载请注明出自www.thecodeway.com哈弗曼编码几乎是所有压缩算法的基础，其实这个算法并不复杂，简单的理解就是，如何用更短的bit来编码数据。 我们知道普通的编码都是定长的，比如常用的ASCII编码,每个字符都是8个bit:字符编码A00101001B00101010C00101011……这样，计算机就能很方便的把由0和1组成的数据流解析成原始信息，但我们知道，在很多情况下，数据文件中的字符出现的概率是不均匀的，比如在一篇英语文章中，字母“E”出现的频率最高，“Z”最低，如果我们使用不定长的bit编码，频率高的字母用 阅读全文
