Question

Grade 12 computer science about recursion

please write in Java

Some conditions

* Returns true if there exists a subset of the items in
* weights[start..weights.length] that sum to goal.
* pre: items in weights[start..weights.length] > 0
* post: true has been returned if there exists a subset
* of items in weights[start..weights.length] that sum to goal.

Thank you very much

A well-known problem in computer science is called the knapsack problem. A variation is as follows:
Given a collection of weights of (possibly) different integral values, is it possible to place some of the
weights in a knapsack so as to fill it to some exact total weight?
For example, if the weights are 3, 5, 6, and 9, then it is possible for such totals as 3, 8, 11, 14, 17,
etc. to be made exactly, but 2, 4, 22, etc. are not possible.
Create a Knapsack application that solves this problem.
