Questions & Step-by-Step Solutions
Which of the following is a valid operation for a queue?
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: Learn the operations of a queue. The two main operations are 'enqueue' and 'dequeue'.
Step 3: 'Enqueue' is the operation used to add an element to the end of the queue.
Step 4: 'Dequeue' is the operation used to remove an element from the front of the queue.
Step 5: Identify which operation is valid for a queue. Both 'enqueue' and 'dequeue' are valid operations.
