Web23 dec. 2024 · Huffman Coding Algorithm - Huffman coding is a lossless data compression algorithm. In this algorithm, a variable-length code is assigned to input different characters. The code length is related to how frequently characters are used. Most frequent characters have the smallest codes and longer codes for least frequent charact Web2 ADVANTAGES: • uniquelydecodable code • smallestaverage codeword length DISADVANTAGES: • LARGE tables give complexity • sensitive to channel errors 1.

Instead of grouping … 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.
