This question is ill-defined. Is it an undirected graph a directed graph or a random graph whose edges are selected with probability p?

jk.
But the code probably looks like this.

GetSubTreeCopy(Node n)
{
	Node n1= new Node();
 	n1.x=n.x;
	if(n.left !=null)
	{
		Node n2= GetSubTreeCOpy(n.left);
		n1.left=n2;
	}
	if(n.right !=null)
	{
		Node n2= GetSubTreeCOpy(n.right);
		n1.right=n2;
	}
	return n1;
}
