WebIntroduction . Counting the number of subsets with a given sum is a standard recursion problem that can be optimized using dynamic programming. It is a variation of the ‘ 0/1 knapsack ’ and the ‘ subset sum ’ problem. We know that dynamic programming can be applied to any problem where the following two properties are being followed. … WebThere are four three element subsets: { frog, duck, elephant }, { frog, elephant, cow }, { frog, cow, duck }, { elephant, cow, duck } Finally, the whole set is a subset of itself: { frog, …
