What are the applications of queues and stacks in computer science?

Queues and stacks are fundamental data structures used in various applications. Queues are often used in scheduling tasks, like print jobs or CPU scheduling, while stacks are used in function calls and backtracking algorithms.

Can you give me an example of how a stack is used in programming?

Sure! A common example is the call stack in programming languages. When a function is called, its context is pushed onto the stack, and when it returns, that context is popped off, allowing the program to resume where it left off.

What about queues? How are they used in real-world applications?

Queues are used in scenarios like managing requests in web servers, where requests are processed in the order they arrive, ensuring fairness and efficiency.

Are there any specific algorithms that utilize these data structures?

Yes, algorithms like Breadth-First Search (BFS) use queues, while Depth-First Search (DFS) typically uses stacks. Both are essential for traversing graphs.
