@Override
public T removeFront() {
	T front = getFront();

	firstNode = firstNode.getNext();

	if(firstNode == null) {
		lastNode = null;
	} else {
		firstNode.setPrev(null);
	}

	return front;
}

Which of the following will NOT happen if removeFront() is called on a deque with 3 items?

• The first node of the three will be removed
• firstNode.data will be returned
