Suppose the object q below is an instance of a class that uses a 'circular array" scheme to implement a quene. Assume that the front and rear markers begin at index 0. Suppose also that the queue has a fixed capacity of 5. That is, there is no array resizing done Which choice below depicts the contents of the internal array after the following sequence of operations? (The array is shown from left to right beginning at index 0. The symbol is used to denote an empty cell.) q. enqueue (1); q. enqueue (2); q. enqueue (3); q. dequeue q. enqueue (4); q. enqueue (5); q. dequeue ) q. enqueue (6); q. dequeue O; q enqueue (7)
