How can you implement a stack using two queues?
- Enqueue elements in both queues and dequeue alternately from each queue.
- Enqueue elements in the first queue and dequeue all but the last element into the second.
- Enqueue elements in the first queue and dequeue them in reverse order.
- Enqueue elements in the second queue and dequeue them in reverse order.
Implementing a stack using two queues involves leveraging the FIFO (First-In-First-Out) property of queues. By carefully enqueueing and dequeuing elements between two queues, we can simulate the behavior of a stack, where the last-in element is the first to be dequeued.
