This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Use the "Improve question" widget to edit your question and provide better information.

Plus, demanding code is a very good way to annoy people, and to get nothing at all...

Solution 1

Toggle a flag that tells if the list is traversed head-to-tail or tail-to-head.
HeadToTail= !HeadToTail;
This is O(1).

Don't forget to modify the list traversal routine to take this flag into account.

No kidding, this IS an acceptable solution.

Yeah i agree no reversing is required for a doubly linked list.
