Given a set S of positive integers, and a positive integer p, our goal is to find the largest integer cp such that there exists a non-empty subset Q of S where the sum of integers in Q is c. For instance, for S={2,3,5,7,10} and p=16, the largest integer c16 is 15 for Q={2,3,10} (a) Describe a dynamic programming algorithm to solve this problem. 1) Describe your subproblems and write a recursive formulation, 2) explain the worst-case asymptotic time complexity of your algorithm, and 3) illustrate (step by step) how your algorithm runs for S={5,7,10} and p=16. No pseudocode is required. (b) State the decision version of this optimization problem, and prove that the decision version is in NP
