When should I use a stack instead of a queue?
Stacks are used for LIFO (Last In, First Out) operations, while queues are for FIFO (First In, First Out).
Can you give me an example of when to use a stack?
Sure! A stack is ideal for undo operations in text editors, where the last action needs to be reversed first.
What about queues? When are they more appropriate?
Queues are great for scheduling tasks, like print jobs, where the first job submitted should be the first to be processed.
Are there any scenarios where I might use both?
Yes! In a web server, you might use a queue to handle incoming requests and a stack to manage the execution of those requests.
