        if(head == null) return null;
        Map<Node,Node> map = new HashMap<>();
        for(Node cur = head; cur != null; cur = cur.next)
            map.put(cur,new Node(cur.val));
        
        for(Node cur = head; cur != null; cur = cur.next)
            map.get(cur).next = map.get(cur.next);
            map.get(cur).random = map.get(cur.random);
        return map.get(head);
