Which data structure is best suited for implementing a LIFO (Last In First Out) system?
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 would organize items if you wanted to follow the LIFO principle. You would need a way to add and remove items from the same end.
Step 3: Consider different data structures. A stack is a data structure that allows you to add (push) and remove (pop) items from the same end.
Step 4: Realize that a stack perfectly matches the LIFO requirement because the last item you push onto the stack is the first one you pop off.
