4: Rafiq has 4 parking spaces in the basement of his apartment. Now, he wants to
know when two adjacent space are open as he doesn’t not want anyone to park next to his
brand-new car. Rafiq already set up a pressure switches in the parking space to detect if the
space is occupied or not and also has 4 logic indicators outside his building. He wants one
logic indicator to activate if two adjacent space become open, another logic indicator to
active if three space become open, a third if all spaces are open and a fourth if one space is
open (in case he chooses to risk it).
