The dequeue operation should throw an exception if it removes the last element in the queue. A. True B. False
Question
The dequeue operation should throw an exception if it removes the last element in the queue. A. True B. False
Solution
B. False
The dequeue operation should not throw an exception if it removes the last element in the queue. Instead, it should simply return that the queue is now empty. Throwing an exception in this case would be inappropriate because removing the last element from a queue is a perfectly valid operation and does not indicate an error condition.
