Huffman Coding is a famous Greedy Algorithm. It is used for the lossless compression of data. It uses variable length encoding. It assigns variable length code to all the characters. The code length of a character depends on how frequently it occurs in the given text. Meer weergeven There are two major steps in Huffman Coding- 1. Building a Huffman Tree from the input characters. 2. Assigning code to the characters by traversing the Huffman Tree. Meer weergeven The time complexity analysis of Huffman Coding is as follows- 1. extractMin( ) is called 2 x (n-1) times if there are n nodes. 2. As extractMin( ) calls minHeapify( ), it takes O(logn) time. Thus, Overall time complexity of … Meer weergeven WebHuffman Coding is a famous Greedy Algorithm.
