What is a typical use case for a stack in real-world applications?
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 a web browser. When you visit a website, it gets added to your history.
Step 3: When you click 'back' in your browser, the most recent website you visited is shown first. This is because the stack removes the last item added.
Step 4: When you click 'forward', the browser goes back to the next website in the stack, which was previously removed when you clicked 'back'.
Step 5: This process of navigating back and forth through your history is a typical use case for a stack.
