WebThis handout contains lots of supplemental background information about Huffman encoding and about file compression in general. It should not be mandatory to read it, but you might find the information interesting, and it could help you to under-stand the algorithm better to see more examples and discussion of it in this document. WebfStep for Huffman Algorithm. Scan text to be compressed and calculate occurrence of all characters. Sort or prioritize characters based on number of occurrences in text. Build Huffman tree based on prioritized list. Perform a traversal of tree to determine all code words. Scan text again and create new file using the Huffman codes.
