Which of the following is a real-world application of stacks?
Step 1: Understand what a stack is. A stack is a data structure that follows the Last In, First Out (LIFO) principle, meaning the last item added is the first one to be removed.
Step 2: Think about how you use text editors, like Microsoft Word or Notepad. When you type and make changes, you might want to go back to a previous version of your text.
Step 3: When you press 'Undo' in a text editor, the program needs to remember the changes you made. It does this by using a stack.
Step 4: Each time you make a change, that change is added to the stack. When you press 'Undo', the most recent change is removed from the stack and reverted.
Step 5: This allows you to go back through your changes step by step, which is a practical use of stacks in real life.
