Given a queue of integers, return the number of integers in the queue. 

Your first line of code must be:
Queue<Integer> queue = new LinkedList<Integer>(list);

queue_numberOfElements([]) → 0
queue_numberOfElements([1, 2, 3]) → 3
queue_numberOfElements([1, 1, 1, 1, 1]) → 5

...Save, Compile, Run (ctrl-enter)

public int queue_numberOfElements(List<Integer> list) { }
