Three persons are involved in processing pizza orders. Person A reads the order from the computer and put the pizza into oven. Person B takes the pizza from oven to quality control desk (QCD). Finally, Person C takes the pizza from QCD and hands it over to the customer. (I know, this is oversimplification. Also, consider, it requires no time to prepare/cook/quality-control the pizza.) Assume all three persons operate on one pizza at a time, both oven and QCD have capacity of one pizza. Write a program (in a programming language you like) to coordinate the three persons using semaphores.

*include the readme file for running the program.
