Which data structure is best suited for implementing a LIFO (Last In First Out) mechanism?
Step 1: Understand what LIFO means. LIFO stands for Last In First Out, which means the last item added is the first one to be removed.
Step 2: Think about how you stack items. If you put a book on top of another book, you have to take the top book off first to get to the one below it.
Step 3: Identify a data structure that works like this. A stack is a data structure that allows you to add (push) and remove (pop) items in a LIFO order.
Step 4: Conclude that a stack is the best choice for implementing a LIFO mechanism.
