C++Jesse the Body-Building Burglar Jesse has broken into a sporting goods store to steal some training equipment. He can only carry out a certain amount of stuff before it gets too heavy. In addition, Jesse can only make one trip in and out of the store before the cops arrive, so he wants to be sure to get the most value out of the stuff he takes. Input for the program will be as below. The first line will contain how much Jesse can carry. This line is followed by a single item per line. Each of these lines will contain the name of the item, the number of items available, each individual item’s weight and its value. There will be up to 10 different items. Output the number of each item type he should take to maximize his value as well as the max value.
