The whole takes 2n time, which is the time complexity of o (n). That is, node d should point to node c, node c to node b, and node b to node a. The keep popping the elements out and updating the doubly linked list.

To Reverse It, We Need To Invert The Linking Between Nodes.

2) call reverse for the rest of the linked list. Return head # reverse the rest list rest = self.reverse (head.next) # put first element at the end head.next.next = head head.next = none # fix the header pointer return rest. The easiest way to think about it is to think like this:
