Interactive Stack Simulator

Interactive Stack Simulator

A responsive, interactive stack simulator that visually demonstrates all stack operations, errors, and concepts with animations and an informational help panel.

Concept: Stack = LIFO (Last In, First Out)

Stack Explained

A stack is a data structure where the last element added is the first one removed. This is called LIFO (Last In, First Out).

Stack Operations:

  • Push(x): Add item x to the top.
  • Pop(): Remove the top item.
  • Peek(): View the top item without removing it.
  • isEmpty(): Check if the stack has no items.
  • isFull(): Check if the stack is full (if size-limited).
  • Clear(): Remove all items from the stack.

Common Errors:

  • Stack Overflow: Trying to push when the stack is full.
  • Stack Underflow: Trying to pop when the stack is empty.

Real-World Examples:

  • Undo/Redo actions in text editors
  • Call stack in programming languages
  • Browser back/forward history

Tips for Using the Simulator:

  • Push items sequentially to see LIFO in action.
  • Use Peek to see the current top without removing it.
  • Clear resets the stack to empty.
  • Try overflow/underflow to understand errors visually.
