Huffman codes 1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s? 2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently use

哈弗曼编码，输入数据后可计算权重.例如，输入11122233334，可得到权重为1,2,3,4 的权重分别为3,3,3,1-the code of Huffman Tree ，this code can compute the weight of you input data
