What are the differences between a queue and a stack?
A queue is a FIFO (First In, First Out) data structure, while a stack is a LIFO (Last In, First Out) structure.
Can you give me examples of where I would use each?
Sure! Queues are often used in scheduling tasks, like print jobs, while stacks are used in function calls and undo mechanisms.
What are the main operations for each data structure?
For a queue, the main operations are enqueue (add) and dequeue (remove). For a stack, they are push (add) and pop (remove).
Are there any real-world applications for these data structures?
Yes! Queues are used in customer service lines, while stacks are used in backtracking algorithms, like maze solving.
