The idea: To encode objects that occur often with a smaller number of bits than objects that occur less frequently. Although any type of objects can be encoded with this scheme, it is common to compress a stream of bytes. Suppose you have the following text, where each character is one byte: so much words wow many compression WebThe Huffman algorithm will create a tree with leaves as the found letters and for value (or weight) their number of occurrences in the message. To create this tree, look for the 2 weakest nodes (smaller weight) and hook them to a new node whose weight is the sum of the 2 nodes.
