-< description of the problem >
+Lets  K be the total nodes in the linked list.
+
+Observation : The Nth node from the end is (K-N+1)th node from the beginning.
+
+So the problem simplifies down to that we have to find  (K-N+1)th node from the beginning.
+
+One way of doing it is to find the length (K) of the linked list in one pass and then in the second pass move (K-N+1) step from the beginning to reach the Nth node from the end.
+To do it in one pass. Let’s take the first pointer and move N step from the beginning. Now the first pointer is (K-N+1) steps away from the last node, which is the same number of steps the second pointer require to move from the beginning to reach the Nth node from the end.
