Let 20 = 1, an = 5a-1 + 3 be the recurrence relation of algorithm A and T(1) = 1, T(n) = 37(n/2)+n be the recurrence relation of algorithm B. 1. Find the solution for both relations. Use any method. 2. Without proof, find Big-Oh for both algorithms. 3. Which algorithm is faster? Justify your answer using Big-Oh notation
