WebHuffman Coding is a famous Greedy Algorithm. It is used for the lossless compression of data. It uses variable length encoding. It assigns variable length code to all the characters. The code length of a character depends on how frequently it occurs in the given text. The character which occurs most frequently gets the smallest code.
