(10 marks) Chapter 4, Programming 10, p. 169.The checkout-line simulation in Figure 4-4 can be extended to investigate important practical questionsabout how waiting lines behave. As a first step, rewrite the simulation so that there are severalindependent queues, as it usually the case in supermarkets. A customer arriving at the checkout areafinds the shortest checkout line and enters that queue. Your revised simulation should calculate thesame results as the simulation in the chapter.I have attached the code so far as a text.
