Question 19 Not yet answered Marked out of 2.00 Flag question Hide sidebars Suppose you are given an implementation of a queue of integers. The operations that can be performed on the queue are: i.isEmpty () - returns true if the queue is empty, false otherwise. ii. deque () - deletes the element at the front of the queue and returns its value. iii. enqueue (1) - inserts the integer i at the Back of the queue. Consider the following function: void f (Aqueue q) { inti; if (qisEmpty() { i = (int)q.dequeue: FI Ti f(q); q.enqueue(i): } ) What operation is performed by the above function f? Select one: } What operation is performed by the above function f ? Select one: O A. Leaves the queue q unchanged OB. Reverses the order of the elements in the queue q O C. Deletes the element at the front of the queue q and inserts it at the back keeping the other elements in the same order O D. Empties the queue
