Build a simulation of waiting queues at an airline check-in counter

>Build an implementation of a queue ADT. >Use this implementation to build a simulation of waiting queues at an airline check-in counter, organized as follows: There are two types of passengers: first class and coach. There are two service stations for first class and three for coach. There is a single queue for each type of passenger (first class, coach). Passenger arrival times are random and are generated by a random number generator. Average arrival rates for passengers are R1 for first class and R2 for coach. These are decided at run-time by prompting the user. Service time is random and varies uniformly between 1 and S1 for first class, and between 1 and S2 for coach. Parameters S1 and S2 are also determined at run-time, by prompting the user. Whenever a service station is available and the corresponding queue is not empty, we pick the passenger at the front of the queue and place her/him on the service station. Whenever a first class service station is available and the first class queue is empty, the service station may service a passenger from coach. The duration of the experiment, in minutes, is decided by the user at run time. Statistics generated by the simulation include: average service time, maximum service time, number served in each class, maximum queue length for each type of passenger.
