To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
