"WebHuffman encoding is doing it using greedy algorithm. In other word, it is not always using 8 bits. Instead, depending on the frequency, we can use 3 bits, 4 bits, or 8 bits etc. By using a table giving how often each character occurs to build an optimal way of representing each character as a binary string.

WebHuffman invented a greedy algorithm that creates an optimal prefix code called a Huffman Code. The algorithm builds the tree T analogous to the optimal code in a bottom-up manner. It starts with a set of C leaves (C is the number of characters) and performs C - 1 'merging' operations to create the final tree.

Webcharacter, a Huffman code uses a variablenumber of bits for each character. With Huffman’s scheme, a common character such as “a” or “e” might be encoded with perhaps just two bits and less frequently used characters like “q” or “#” would be encoded with a longer bit string.
