Consider the table above that represents the frequencies of characters in a document.

WHILE there is more than one node in the list     Select the two nodes with the smallest frequencies.     Join them into a new node.     New frequency = first frequency + second frequency.     Put the new node back into the list. END WHILE The last remaining node is the root of the Huffman tree. Assign:    0 to every left branch    1 to every right branch The code for each character is the path from the root to that character. STOP
