Description: Huffman encoding can be used to construct the shortest length of the message' s encoding scheme. Specifically, the following: Let coded character set needed for the {d1, d2, ..., dn}, number or frequency in which they appear in the message set is {w1, w2, ..., wn}, with d1, d2, ..., dn a leaf node, w1, w2, ..., wn as their weights, a Huffman tree structure, the predetermined Huffman tree represents 0 left branch and right branch represents 1, from the root to every sequence of a leaf node path through a branch consisting of 0 and 1, then the corresponding node encoded characters that we call Huffman coding.
