12 Points W Let ao = 1. an-an-1 + 2 be the recurrence relation of algorithm A and T(1) = 1, T(n) = 7T(n/4)+n be the recurrence relation of algorithm B. 1. Find the solution for both relations using the Characteristic Polynomial method. 2. Without proof, find Big-Oh for both algorithms. 3. Which algorithm is faster? Justify your answer using Big-Oh notation
