Huffman's tree

Web10 aug. 2024 · Since Huffman coding is a lossless data compression algorithm, the original data will always be perfectly restructured from the compressed data. Suppose we would like to encode the following phrase: “CALL ME MELLOW FELLOW”. One way to do that would be to represent each symbol as a unique pattern of bits. WebA Huffman code is a “type of optimal prefix code that is commonly used for lossless data compression”. There are three parts of that definition we have to unpack: “code”, “prefix”, and “optimal”. In this context, a “code” is a mapping from symbols to bit strings. For example, ASCII is a character encoding that maps from ...
