Description: 迄今为止见过的最方便的huffman编码，效率很高
一个外国人写的，很具有研究价值
Constructing a Huffman Tree according to the number of times each symbol appears in the data stream:
1) Create an array of N nodes, representing N possible symbols (ranging between 0 and N-1).
2) Set the value of each node to the number of times that its symbol appears in the data stream.
3) Create a Minimum-Heap of N nodes.
4) Add every node whose value is greater than zero to the heap.
5) Extract the best two nodes in the heap.
6) Create a parent node whose children are the two extracted nodes.
7) Add the parent node to the heap.
8) Repeat the previous three steps N-1 times (until only 1 node remains in the heap).
9) Extract the last node in the heap.
The array created in the first step stores the leaves of the tree, and is used in order to encode the data stream.
The node extracted in the last step is in fact the root of the tree, and is used in order to decode the data stream. Platform: |

Description: huffman编码.
把一个英文字母,空格,句号.一共有28个 character.
先求每个字符出现的频率.
然后用频率对这个文件进行哈夫曼编码.
然后再进行解码.
运行的时候需要在VC++ 工程->设置->调试->程序变量里加E:\sample.txt E:\encode.txt E:\decode.txt
然后把英文文件放到E盘里.名叫samole.txt,
还有在E里新件2个txt文件.名叫encode.txt,decode.txt.
编码后的二进制save到encode.txt,解码后的英文字符save到decode.txt了.-Huffman coding. One English letters, spaces, full stop. A total of 28 character. Every character in first seeking the frequency. Then the frequency of text pieces for Huffman coding. then decode. When running in VC- Platform: |
