A basic brute force solution could be to try all combinations of the given items to choose the one with maximum profit and a weight that doesnt exceed C. Heres what our algorithm will look like: create a new set which includes one quantity of item i if it does not exceed the capacity, and, create a new set without item i, and recursively process the remaining items, return the set from the above two sets with higher profit. One type of base case is to stop recursing for an input that exists at the edge of the possible range of inputs.
