What are stacks in computer science?
Stacks are data structures that follow the Last In, First Out (LIFO) principle, meaning the last item added is the first to be removed.
Can you give me an example of how a stack works?
Sure! Imagine a stack of plates. You can only add or remove the top plate. If you add a plate, it goes on top, and when you remove one, you take the top plate off.
What are some common applications of stacks?
Stacks are used in various applications like function call management in programming, undo mechanisms in software, and parsing expressions.
How do stacks differ from queues?
Stacks use LIFO, while queues use First In, First Out (FIFO). In a queue, the first item added is the first to be removed.
