The huffman code

WebTugas mata kuliah Algoritma Design and Analysis Kelompok 1 dengan materi Penerapan Algoritma Huffman Code untuk Kompresi Data Teks 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.

WebA Huffman code is closely related to a binary tree, however unlike a binary tree a Huffman code only stores its information in the leaf nodes. The optimal input for Huffman compression is one where the output tree is fully balanced. I.e. where all letters of the Huffman alphabet are equally likely, but where more bits are used in the encoding ...
