Q: In a queue, which operation is performed in constant time?

Solution: All operations (enqueue, dequeue, and peek) can be performed in constant time O(1) in a properly implemented queue.

Steps: 5

Step 1: Understand what a queue is. A queue is a data structure that follows the First In First Out (FIFO) principle, meaning the first element added is the first one to be removed.
Step 2: Identify the main operations of a queue: enqueue (adding an element), dequeue (removing an element), and peek (viewing the front element without removing it).
Step 3: Learn about constant time operations. An operation is in constant time O(1) if it takes the same amount of time to complete, regardless of the size of the queue.
Step 4: Realize that in a properly implemented queue, all three operations (enqueue, dequeue, and peek) can be done in constant time O(1). This means they are efficient and quick.
Step 5: Conclude that the answer to the question is that all operations in a properly implemented queue can be performed in constant time.
