Draw a system/level-0 diagram for this scenario: You are developing a new customer relationship management system for the BEC store, which rents out movies to customers. Customers will provide comments on new products, and request rental extensions and new products, each of which will be stored into the system and used by the manager for purchasing movies, extra copies, etc. Each month, one employee of BEC will select their favorite movie pick of that week, which will be stored in the system. The actual inventory information will be stored in the Entertainment Tracker system, and would be retrieved by this new system as and when necessary. Example of what a level-0 diagram looks like is attached.

The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns. b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9. c.
