WebHuffman invented a greedy algorithm that creates an optimal prefix code called a Huffman Code. The algorithm builds the tree T analogous to the optimal code in a bottom-up manner. It starts with a set of C leaves (C is the number of characters) and performs C - 1 'merging' operations to create the final tree. Web4 apr. 2024 · A Computer Science portal for geeks.

WebStep 1: According to the Huffman coding we arrange all the elements (values) in ascending order of the frequencies. Step 2: Insert first two elements which have smaller frequency. Step 3: Taking next smaller number and insert it at correct place. Step 4: Next elements are F and D so we construct another subtree for F and D. WebHuffman 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. The character which occurs most frequently gets the smallest code.
