In this algorithm a variable-length code is assigned to input different characters. The code length is related with how frequently characters are used. Most frequent characters have smallest codes, and longer codes for least frequent characters. There are mainly two parts.

WebbThe algorithm for Shanon-Fano coding is: 1) Parse the input and count the occurrence of each symbol. 2) Determine the probability of occurrence of each symbol using the symbol count. 3) Sort the symbols according to their probability of occurrence, with the most probable first. 4) Then generate leaf nodes for each symbol.
