Question: Consider the following operations on a Queue data structure that stores int values. ( enqueue puts item in a queue, whereas dequeue remoyes items )

Consider the following operations on a Queue data structure that stores int values. (enqueue puts item in a queue, whereas dequeue remoyes items)
Queue q= new Queue();
q.enqueue(3);
q.enqueue(5);
q.enqueue(9);
System.out.println(q.dequeue());
q.enqueue(2);
q.enqueue(4);
System,out.println(q.dequeue());
System.out.println(q.dequeue()); //d3
q.enqueue(1);
q.enqueue(8);
What value is returned by the last dequeue operation (denoted above with a d3 in comments)?
