Programming homework1) Simulated waiting queue in an Indian post office: In an Indian post office that not only distributes mail but also performs some financial activities like a savings bank, a lone postal worker attends to a single lineup of clients. As soon as a consumer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the queue while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time.i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished.
Objective: Student should be able to develop the programs for queue using arrays and linked list Exercise 1: Implementation of Queue using Array or Linked list Consider a real life situation. design a simulation that can help to answer it. Cars lined up at a car wash have 3 line need to consider where need to line up(pick the less car) Be sure to state any assumptions that you make and provide any probabilistic data that must be considered as part of the scenario.
Goal: develop a class Queue, an ordered collection of objects that restricts insertions to the rear of the queue and removal from the front of the queue •The class Queue should support methods: • . Queue (): Constructor that initializes the queue to an empty queue enqueue (item): Add item to the end of the queue dequeue (): Remove and return the element at the front of the queue isEmpty(): Returns True if the queue is empty, False otherwise appts Queue () >>> appts.enqueue ('John') >>> appts.enqueue ('Annie') >>> appts.enqueue ('Sandy') >>> appts.dequeue () 'John' >>> appts.dequeue () 'Annie' >>> appts.dequeue () 'Sandy' >>> appts.isEmpty() True
