Question

In a queue, a dequeue operation always removes an element. Group of answer choices:

a) The front
b) The middle
c) The back
d) A random

Answer 1

A dequeue operation always removes an element from the front of the queue, adhering to the First-In, First-Out principle.

The Correct Option is; a) The front.

Step-by-step explanation:

In a queue, a dequeue operation always removes an element from the front of the queue. This is because a queue is designed to function as a First-In, First-Out (FIFO) data structure, meaning that the first element added to the queue is the first one to be removed. A dequeue operation is contrasted with an enqueue operation, which adds an element to the back of the queue.

In a queue, a dequeue operation always removes an element. This operation is performed on the front of the queue. When a dequeue operation is executed, the element at the front of the queue is removed and the next element becomes the new front.
