Which of the following is a real-world application of a stack?
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 we use text editors. When you type something and then make a mistake, you often want to go back to what you had before.
Step 3: Realize that when you make changes in a text editor, each change is saved in a stack. The most recent change is on top.
Step 4: When you press 'undo', the text editor removes the top change from the stack, reverting to the previous state.
Step 5: Conclude that this is a real-world application of a stack, as it helps manage changes in a way that allows easy reversion.
