This project is designed to practice with linked list, queue, simulation, and your C++/Java programming skill (and possibly vector, list, or sequence). Make sure to fully utilize OOP approach. ABC Calling Center would like to provide adequate service representatives to staff its calling basically a queue object and you can assume one customer representative per line. After some analysis, you decided to implement a LinkedQueue class to perform the simulation as described below (i.c., linked list must be used to implement a queue and relevant information for each customer should be stored in a node). Based on some preliminary estimate, customers are expected to call in random integer intervals of 1 to n minutes (inclusively and two customers are expected to call between that interval so if customer 1 calls at minute 3, then customer 2 is expected to call between minute 4 and 7 when n is 4). Also, it is expected to take a random integer interval of 1 to m minutes to serve each customer. If the call arrival rate is faster than the service rate (n
