Huffman code using greedy method

Web23 jun. 2024 · There are mainly two major parts in Huffman Coding: 1) Build a Huffman Tree from input characters. 2) Traverse the Huffman Tree and assign codes to characters. Steps to build Huffman Tree: Input is an array of unique characters along with their frequency of occurrences and output is Huffman Tree. 1. Webbefore. The Huffman coding theory has been one of the best coding methods for data compression without loss of information. It relies heavily on a technique called a greedy algorithm, a process that “greedily” tries to find an optimal solution global solution by solving for each optimal local choice for each step of a problem.
