Question

Suppose the following operations are performed on an empty queue:\ enqueue (5): enqueue (7): dequeue (): enqueue (9): enqueue (12): dequeue (): enqueue (10): Insert numbers in the following diagram to show what will be stored in the static queue after the operations have executed.

Short answer

**Answer:** The final state of the static queue is Q = [9, 12, 10].

Step-by-step solution

Start with an empty queue

Initially, the queue is empty: Q = []

Enqueue 5

Execute the first operation (enqueue 5) by adding the number 5 to the end of the queue: Q = [5]

Enqueue 7

Execute the second operation (enqueue 7) by adding the number 7 to the end of the queue: Q = [5, 7]

Dequeue

Execute the third operation (dequeue) by removing the first element (5) from the queue: Q = [7]

Enqueue 9

Execute the fourth operation (enqueue 9) by adding the number 9 to the end of the queue: Q = [7, 9]

Enqueue 12

Execute the fifth operation (enqueue 12) by adding the number 12 to the end of the queue: Q = [7, 9, 12]

Dequeue

Execute the sixth operation (dequeue) by removing the first element (7) from the queue: Q = [9, 12]

Enqueue 10

Execute the seventh operation (enqueue 10) by adding the number 10 to the end of the queue: Q = [9, 12, 10]

Final State of the Queue

The final state of the static queue after performing all the given operations is Q = [9, 12, 10].
