WebNov 8, 2011 · You know that the answer is wrong, because the Huffman dictionary is less than 4 bits per character, so the real answer must be less than .5. If the dictionary and character frequency doesn't change for longer strings, then the compression ratio shouldn't decrease toward an asymptotic limit as the string gets longer.
