Webcharacter, a Huffman code uses a variablenumber of bits for each character. With Huffman’s scheme, a common character such as “a” or “e” might be encoded with perhaps just two bits and less frequently used characters like “q” or “#” would be encoded with a longer bit string. Consequently, WebQ. What is the average size in bits of letters in this text given c() above? A. 2*f a + 2*f e + 3*f k + 2*f l + 3*f u = 2.3 Definition.
