About unbounded knapsack, how to figure out which items are included & how many times?

[kuchaguangjie]

For knapsack 0/1, could figure out which items are included from the resulting 2d array.

But, for the knapsack - unbounded, I have checked KnapsackUnbounded.java, and then searched on Google, but didn't found a solution, to figure out which items are included and how many times each item is included.

Could you clarify whether this can be done, and if yes, how? Many thanks.

(BTW: Maybe this worth another video:)
