Questions & Step-by-Step Solutions

What is the primary advantage of using a queue over an array?
  • Step 1: Understand what a queue is. A queue is a data structure that stores items in a specific order.
  • Step 2: Learn about the First-In-First-Out (FIFO) principle. This means that the first item added to the queue will be the first one to be removed.
  • Step 3: Compare this with an array. An array allows access to any item directly, but does not have a specific order for adding and removing items.
  • Step 4: Recognize that the FIFO nature of a queue is useful for certain tasks, like processing tasks in the order they arrive.
  • Step 5: Conclude that the primary advantage of a queue over an array is its FIFO operation, which helps manage items in a predictable order.
