WebHuffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree. Huffman Coding prevents any ambiguity in the decoding process using the concept of prefix code ie. a code associated with a character …
