We use Huffman's algorithm to obtain an encoding of alphabet {a, b, c} with frequencies fa, fb, fc. Which of the following codes cannot possibly be obtained (no matter what the frequencies are)
Code 1 = {0, 10, 11}
Code 2 = {0, 1, 00}
Code 3 = {10, 01, 00}
(A) Only code 2
(B) Only code 2 and code 3
(C) Only code 1 and code 3
(D) None
answer given -(B)
why code 3 is incorrect??
