In question #2, which of the following represents the word “dead”?
(C) Both A and B
(D) None of these
Explanation: The Huffman Tree generated is:
character code-word f 0 c 100 d 101 a 1100 b 1101 e 111
The word dead can be represented as:
101 111 1100 101
However, the alternative codeword can also be found by assigning 1 to the left edge and 0 to the right edge of the tree, i.e. dead can also be represented as:
010 000 0011 010
