贪心算法有很多经典的应用,比如霍夫曼编码(Huffman Coding)、Prim 和 Kruskal最小生成树算法、还有 Dijkstra 单源最短路径算法。最小生成树算法和最短路径算法我们后面会讲到。今天来看下,霍夫曼编码,它是如何利用贪心算法来实现... 【贪心算法】:如何用贪心算法实现Huffman压缩编码?

When I got to the section on Huffman coding, it reminded me of how much I enjoyed implementing the algorithm a a few years back, that time in C. So I decided I should try again, this time in F#![ Note: If you are more interested in F# than in Huffman Coding, feel free to skip...

一、 需求分析 1. 本演示程序中，模拟的是小写26个英文字母的Huffman压缩，字母小随机函数随机产生，后统计字母个数建立Huffman树，用建立Huffman树将字母转为二进制流，再将二进制流每次分8个转为一个Unsigned Char写入物理内存！2. 解压时建立同样的Huffman树或读取已保存的Huffman树，通过将读取的Unsigned Char...
