Which of the following is a valid 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 actions are performed in a text editor. When you type or make changes, each action can be considered an item that is added to the stack.
Step 3: When you want to undo an action, the most recent action (the last one added to the stack) is removed first, effectively reversing that action.
Step 4: Realize that this behavior of adding and removing actions makes stacks a perfect fit for implementing undo functionality in text editors.
