信息论中变长编码的香农编码程序，大家可以互相学习-Variable-length coding in information theory Shannon coding procedures, we can learn from each other

Huffman and Shannon-Fano source coding

对通信中的信源的二进制编码的实现，有香农编码，费诺编码以及霍夫曼编码-Source of communication in the realization of the binary code, there is the Shannon coding, coding, and Huffman coding Fenno

This technique doesn t involve sorting of probabilities as in Shannon-Fano coding. The following formula is used to calculate F (x) which in turn generates the code F (x) = F(x) + p(x) / 2, where F(x) is cummulative sum of probabilities p(x).
