In a queue, which operation is performed to remove an element?
Step 1: Understand what a queue is. A queue is a collection of items where the first item added is the first one to be removed.
Step 2: Learn about the FIFO principle. FIFO stands for First In, First Out, meaning the first element added to the queue will be the first one to be removed.
Step 3: Identify the operation for removing an element. The operation used to remove an element from a queue is called 'Dequeue'.
Step 4: Remember that when you dequeue, you take out the element that has been in the queue the longest.
