Web21 jan. 2024 · Of course the huffman code will be A: 0 and B: 1. The expected length is L ( C) = p A × 1 + p B × 1 = 1 . The entropy is H ( S) = − p A log p A − p B log p B . We know that if p A approaches 0, then H ( S) approaches 0 too. So L ( C) − H ( S) approaches 1. Share Cite answered Sep 5, 2024 at 21:26 mnz 317 1 8 Add a comment thai restaurants south loop chicago
