Its easy to get lost in so much information: which is why you should make a plan on how you will get interview-ready. Even when its clear that a problem can be solved using Dynamic Programming (which is also difficult), it can be challenging to even know where to start on the solution. 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.
