WebHuffman coding is a form of lossless compression which makes files smaller using the frequency with which characters appear in a message. This works particularly well when … WebThe Huffman algorithm considers the two least frequent elements recursively as the sibling leaves of maximum depth in code tree. The Fibonacci sequence (as frequencies list) is defined to satisfy F (n) + F (n+1) = F (n+2). As a consequence, the resulting tree will be the most unbalanced one, being a full binary tree.
