Review the SUBSET-SUM prоblem, аnd then аnswer the prоmpt. SUBSET-SUM Prоblem Given а set of non-negative integers, and another non-negative integer , we wish to decide whether there exists some subset of whose sum of elements is equal to . For example, if ={4,7,1,9} and =16, the decision here must be yes since {7,9} is a subset of whose elements sum to value exactly 16. Our approach to solve this problem will be to apply dynamic programming. We will do exactly this using a recursive algorithm, though we will be more clever about how to handle overlapping subproblems. Denote this algorithm as . For our recursive algorithm , we first define a subproblem : is true if there exists a subset of elements
