It creates a lookup table for the most-significant nine bits of the code. Each entry in the table has either a symbol and numbers of bits for that code (less than or equal to nine), or if the provided nine bits is a prefix of a longer code, that entry has a pointer ...

WebSince it’s creation by David A. Huffman in 1952, Huffman coding has been regarded as one of the most efficient and optimal methods of compression. Huffman’s optimal compression ratios are made possible through it’s character counting functionality. Unlike many algorithms in the Lempel-Ziv suite, Huffman encoders scan the file and generate ...
