Huffman Coding - Huffman Coding Compression Algorithm

WebWith Huffman coding, does it take every 2 bits, so 00, 01, 10, or 11, convert them to a, g, t, or c, and then re-convert them to binary as 1, 00, 010, and 001 based on which appears most often? What if the letters appear the same amount of times so that Huffman coding expands it rather than compressing? • ( 11 votes) Baraka Mujtaba 3 years ago Hi.
