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.

WebHuffman coding (also known as Huffman Encoding) is an algorithm for doing data compression, and it forms the basic idea behind file compression. This post talks about the fixed-length and variable-length encoding, uniquely decodable codes, prefix rules, and Huffman Tree construction. Overview
WebStep by Step example of Huffman Encoding. Let's understand the above code with an example: Character :: Frequency a :: 10 b :: 5 c :: 2 d :: 14 e :: 15.
