1. An opaque urn contains three diamonds, four rubies, and two pearls. Construct a flowchart that describes the following events: Take a gem from the urn. If it is a diamond, lay it aside. If it is not a diamond, return it to the urn. Continue in this fashion until all the diamonds have been removed. After all the diamonds have been removed, repeat the same procedure until all the rubies have been removed. After all the rubies have been removed, continue in the same fashion until all the pearls have been removed.
2. Develop a high-level class diagram that shows the relationships among a manufacturer's inventory of finished products in its warehouses. The company has many warehouses that are managed by the inventory-control supervisor. Each warehouse contains many bins of products. Each bin contains one product type.
