How can you implement a queue using stacks efficiently?

To implement a queue using stacks efficiently, you can use two stacks. One stack is used for enqueueing elements, and the other stack is used for dequeueing elements. When dequeueing, if the dequeue stack is empty, you can transfer elements from the enqueue stack to the dequeue stack to maintain the order of elements. This approach allows for efficient implementation of a queue using stacks.
