Implement a queue using stacks.

public class Queue<T>
{
	private readonly Stack<T> _front;
	private readonly Stack<T> _helper;

	public Queue()
	{
		_helper = new Stack<T>();
		_front = new Stack<T>();
	}

	public void Enqueue(T data)
	{
		_front.Push(data);
	}

	public T Dequeue()
	{
		while (_front.Any())
		{
			_helper.Push(_front.Pop());
		}

		T data = _helper.Pop();

		while (_helper.Any())
		{
			_front.Push(_helper.Pop());

		}

		return data;
	}

	public T Peek()
	{
		while (_front.Any())
		{
			_helper.Push(_front.Pop());
		}

		T data = _helper.Pop();
		_front.Push(data);

		while (_helper.Any())
		{
			_front.Push(_helper.Pop());

		}

		return data;
	}
