这是本人编写的一个Huffman压缩算法,压缩效率最好能达到％20左右,已将所有的编码串转换成为二进制码-This is the one I prepared Huffman compression algorithm, the best compression efficiency can reach about 20%, All the coding has become a string of binary code

费诺编码，使用STL实现。包含计算平均码长和编码效率功能-charges Connaught coding, the use of STL achieve. Includes calculation of the average code length coding efficiency and function
