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 used messages.

3.This problem can be solved by using an extended binary tree which is used in the 2-way merging problem.



the sourse code is

to encode and decode the Huffman.
