WebHuffman Encoding is an algorithm where optimal prefix code is used for compressing data without losing information. Here prefix code means the unique bit sequence assigned to … Adaptive Huffman coding (also called Dynamic Huffman coding) is an adaptive coding technique based on Huffman coding. It permits building the code as the symbols are being transmitted, having no initial knowledge of source distribution, that allows one-pass encoding and adaptation to changing conditions in data. The benefit of one-pass procedure is that the source can be encoded in real time, though it bec…
