When popping an element off the top of a stack, the usual procedure is to first access the element with the
top function to see what you’re about to remove, and then call pop to actually remove it. This ensures you know the value being processed before it’s gone! If you’re not following this order, you might end up losing access to that information — and that’s a classic stack blunder!In real-world applications, stacks are used in various systems like function call management in programming and undo mechanisms in software. For example, when you press “undo” in your favorite text editor, the editor is typically using a stack to keep track of all your actions, allowing you to step back through your typing history efficiently! So, just like in our stack operation, order matters!
