About This Simulator

Understand the fundamental difference between stacks (LIFO) and queues (FIFO) through interactive visualization. Push and pop elements onto a stack, or enqueue and dequeue from a queue. Watch elements animate in and out with color-coded operations, and see how each data structure processes elements in a completely different order.

How It Works

  1. Switch between Stack and Queue mode using the tabs
  2. Type a value and click Push/Enqueue to add it
  3. Click Pop/Dequeue to remove an element
  4. Watch the animation to see LIFO vs FIFO behavior
  5. Click Clear to empty the data structure
