I am looking for a solution with no 'tail' node available/static types
used etc.
Also with algorithms given without above two conditions, i don't see
they doing the right thing for me. Maybe i need to check more.
Have you guys tried to see if this is working for you?

initial call to this will be rev(head);

Hi,
I was trying to accomplish this task with the following call , header
= ReverseList(header)
I don't want to pass tail pointer or anything and just want that i get
a reversed list with new header properly assigned after this call. I
am getting issues in corner conditions like returning the correct node
to be assigned to header.
Can anyone give an elegant solution with above requirement? Since it
is with recursion, please test for multiple scenarios (empty list, one
node list, twe nodes
list etc) before posting your solution. In case
of empty list, the procedure should report that.
