Question
In a nonempty queue if front=rear, it means
Solution
In a nonempty queue, if front=rear, it means that there is only one element in the queue.
Here's the step by step explanation:
-
A queue is a data structure that follows the FIFO (First In First Out) rule. This means that the first element that is added to the queue is the first one to be removed.
-
In a queue, we maintain two pointers, front and rear. The front pointer points to the first element in the queue and the rear pointer points to the last element in the queue.
-
When we add an element to the queue, we add it at the rear and when we remove an element, we remove it from the front.
-
If the queue is nonempty and the front pointer is equal to the rear pointer, it means that there is only one element in the queue. This is because both the front and rear pointers are pointing to the same element.
-
Therefore, in a nonempty queue, if front=rear, it means that there is only one element in the queue.
