Questions & Step-by-Step Solutions

What happens when you try to enqueue an element into a full queue?
  • Step 1: Understand what a queue is. A queue is a data structure that holds elements in a specific order, like a line of people waiting for something.
  • Step 2: Know what 'enqueue' means. Enqueue is the action of adding an element to the back of the queue.
  • Step 3: Recognize what a 'full queue' is. A full queue means that it has reached its maximum capacity and cannot hold any more elements.
  • Step 4: Try to enqueue an element into the full queue. This means you are attempting to add another item to the queue.
  • Step 5: Check the result of the enqueue action. Since the queue is full, it cannot accept the new element.
  • Step 6: Understand the outcome. An error is raised, indicating that the queue is full and cannot accept more elements.
