01 the problem of obtaining and not obtaining a backpack is actually an opportunity cost problem. If you take something, although the current value has increased for the moment, you have paid the opportunity cost. If not, the space left may be more valuable in the future. Therefore, space and value are always in conflict. Our goal is to use limited space to load the best value.
Given weights and values of n items, put these items in a knapsack of capacity W to get the maximum total value in th
