2. Suppose we have a knapsack that can hold at most 7 pounds. The table below lists the weight and value of four items: item weight value 1 2 pounds $3.00 2 3 pounds $2.00 3 4 pounds $4.00 4 5 pounds $1.00 Use dynamic programming to solve the 0-1 knapsack problem and determine what items we should pack in the knapsack to achieve the maximum total value of packed items. Show your work (i.e., show the dynamic-programming table).
