Explain an algorithm that computes 2^n using (log n) multiplications. Justify why your algorithm uses (log n) multiplications.a. Consider the case where n is a power of 2, i.e., n = 2^k . Use (k) multiplications to obtain 2n . Hint: Note that 2^(2^k) = (2^(2^k1) )^2 .b. Consider the case where n = 2^k + 2^(k1) . Use (k) multiplications to obtain 2^n . Hint: Note that 2^(2^k+2^(k1)) = 2^(2^k) 2^(2^(k1)) .c. Generalize the ideas in parts (a) and (b) to compute 2n using (log n) multiplications for any positive integer n.
