Question
What happens when you try to enqueue an element into a full Circular Queue?a)The oldest element in the queue is automatically dequeued.b)The new element is placed at the front of the queue.c)An error is thrown, and the enqueue operation fails.d)The new element overwrites the oldest element in the queue.
Solution
c) An error is thrown, and the enqueue operation fails.
When you try to enqueue an element into a full circular queue, the queue operation fails and an error is thrown. This is because a circular queue has a fixed size, and when all the spaces in the queue are filled, there is no room to add another element. The queue operations must then wait until an element is dequeued, or removed, from the queue to make space for the new element. This is a property of queue data structures in general, not just circular queues.

Suppose that Q is a queue implemented with a circular array A, initially empty (with size/capacity = 0). You run the following operations in the order given:1. Q.enqueue(7) 2. Q.enqueue(42) 3. Q.enqueue(3) 4. Q.dequeue()5. Q.enqueue(10)6. Q.first()7. Q.enqueue(5)8. Q.enqueue(30)9. Q.enqueue(15)10. Q.dequeue()11. Q.dequeue()12. Q.dequeue()13. Q.dequeue()14. Q.dequeue()Assuming that insertion and deletion in dynamic arrays use the resizing strategy we have seen during the lectures, describe the entries of the array A after performing the above operations, separating each entry by a comma and no space. If an entry is empty, write "None" (case-sensitive). For example, if the array was [1, 2, None, None], then write "1,2,None,None", omitting the double quotes.
The dequeue operation should throw an exception if it removes the last element in the queue. A. True B. False
