Given a set of items, each with a weight and a value, determine the number of each item to include in a collection so that the total weight doesnt exceed a given limit and the total value is as large as possible. I just listed these links for my personal Practice. Using a memoized approach, weve improved the algorithms average run time efficiency to O(n + d) by adding previously seen values to a set collection object.

Weve learned that dynamic programming isnt a specific design pattern as it is a way of thinking. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later. Without going into the details of big-O notation, we can assume this type of solution would have an average runtime of O(n ^ 2)time or greater, mainly because our algorithm works by comparing each value with every other value.
