How Do Stacks and Queues Handle Data in Different Ways?

Stacks and queues are two basic ways to organize data. They both help manage information, but they do it in different styles.

Stacks:

• What is a Stack? A stack is like a pile of books. You can only take the book on the top first. This is called the Last In, First Out (LIFO) method.
• What Can You Do with a Stack?
  • Push: This means adding a new item on top.
  • Pop: This means taking away the item from the top.
• When Do We Use Stacks? We often use stacks for things like managing tasks in computer programs or allowing users to undo actions.
• Example: If you add the numbers 1, 2, and 3 to a stack (push), and then you take them out (pop), they will come out in this order: 3, 2, 1.

Queues:

• What is a Queue? A queue is like a line of people waiting for a bus. The first person in line is the first to get on the bus. This is called the First In, First Out (FIFO) method.
• What Can You Do with a Queue?
  • Enqueue: This means adding a new item at the end of the line.
  • Dequeue: This means removing the item at the front of the line.
• When Do We Use Queues? Queues are useful for organizing tasks like scheduling jobs or handling requests for websites.
• Example: If you add the numbers 1, 2, and 3 to a queue (enqueue), when you take them out (dequeue), they will come out in this order: 1, 2, 3.

In short, stacks and queues are both useful for organizing data, but stacks use the LIFO order while queues use the FIFO order.
