Program Plan Intro

Queue:

  • A queue contains sequence of items.
  • The item which is inserted first is retrieved first.
  • Queue performs “First In First Out”.

Operations performed on Queue:

A queue can perform two operations. They are:

  • Enqueue
  • Dequeue

Enqueue:

Insertion of an element into the queue is called as Enqueue. The elements can be inserted at any end of the queue. The sides in which the items are inserted are called as “Rear”.

Dequeue:

Retrieving an element from the queue is known as Dequeue. The sides in which the items are deleted are called as “Front”.

java data structure   Queue: Q4: A program performs the following operations on an empty queue Q: Q.enqueue(24) Q.enqueue(74) Q.enqueue(34) Q.first() Q.dequeue() Q.enqueue(12) Q.dequeue() Please show the queue contents at the end of these operations. Clearly show the front of the queue.
Note : addqueue works like Enqueue and deleteQueue works like Dequeue Consider the following statements: (8, 9) queueType queue; int num; Show what is output by the following segment of code num = 7; queue.addQueue (6); queue.addQueue (num); num = queue.front (); queue.deleteQueue(); queue.addQueue (num + 5); queue.addQueue (14); queue.addQueue (num queue.addQueue (25); queue.deleteQueue (); 2); cout <« "Queue elements: "; while (!queue.isEmptyQueue ()) { cout <« queue.front () << " "; queue.deleteQueue(); } cout <« endl; Queue elements: 14 14 4 25 Queue elements: 11 14 4 4 Queue elements: 11 14 4 25 Queue elements: 11 14 25 25
Explain how a queue works along with the enqueue and dequeue operations with front and rear pointers.
