WebThere are two main types of entropy coders, Huffman and arithmetic. Huffman’s big advantage is speed, while arithmetic coding gives better compression. Deflate chose to use Huffman, and even today, it’s a good tradeoff in speed vs compression. But before we implement Huffman, we need to be able to read and write bits, not bytes.

Huffman’s procedure creates the optimal code for a set of symbols. It is uniquely decodable, because any string of code symbols can be decoded in only one way. Example Reduction
