Find a recurrence relation for the following problem in terms of smaller subproblems: Given an array A of integers and a number target, what is the size of the largest subset of A whose sum is less than or equal to target? For example, if A = [2, 5, 5, 2] and target = 10, then the answer is 3 because although the subset 5, 5 sums to 10 and the subset 2, 5, 2 sums to 9, the second solution has corresponds to a subset of size 3 rather than 2. (Include the base case. You may give your answer in math notation, code or pseudocode. Solve the general problem, not just the example.)
