Many variations of Huffman coding exist, some of which use a Huffman-like algorithm, and others of which find optimal prefix codes (while, for example, putting different restrictions on the output). Note that, in the latter case, the method need not be Huffman-like, and, indeed, need not even be polynomial time. The n-ary Huffman algorithm uses the {0, 1,..., n − 1} alphabet to encode message and build a… WebHuffman coding is an entropy encoding algorithm length codes.used for lossless data compression.
