Example Code Ch 13-5
Consider the following operations on a queue data structure that stores int values:
Queue q = new Queue() ;
q.enqueue(3) ;
q.enqueue(5) ;

q.enqueue(4) ;
System.out.println(q.dequeue() ) ; // d2
System.out.println(q.dequeue() ) ; // d3
q.enqueue(1) ;
q.enqueue(8) ;
-Refer to Example Code Ch 13-5: If we replace the System.out.println statements (denoted in comments as d1, d2 and d3) with the statement q.enqueue(q.dequeue() ) ; q would contain which order of int values after all instructions have executed?
