Web11 aug. 2024 · Accordingly, when a data is encoded with Huffman Coding, we get a unique code for each symbol in the data. For example the string “ABC” occupies 3 bytes without any compression. Let’s assume while the character A is given the code 00, the character B is given the code 01, the character C is given the code 10 as the result of encoding. WebWe have explored Huffman Encoding which is a greedy algorithm that encodes a message into binary form efficiently in terms of space. It is one of the most successful Encoding …

WebIn this code, we can encode the string xyz with the bit string 101001, and we can decode the result without ambiguity.. So that’s what it means to say that a Huffman code is a prefix code; finally, Huffman codes are “optimal” in the sense that they give short codes to the most common symbols and longer codes to the least common symbols. WebHuffman Coding implements a rule known as a prefix rule. This is to prevent the ambiguities while decoding. It ensures that the code assigned to any character is not a prefix of the code assigned to any other character.
