1. Draw the control flow graph and design test cases to perform basic path testin

2. Implement Junit code to run test cases for each path

3. design test cases for D-U path testing for variables occupancyRate and totalOccupied.

4. Identify bugs in the program using test cases b and c above and fix them

// These are located on floors 10-16. There is no 13th floor.
