Reverse

Three tiny puzzles:

1. Given the following interface:
   
   
   interface INode
   {
            INode Next { get; set; }
            object Data { get; }
   }
   
   and a reference to root INode root reverse a one-linked list. Do not use any additional collections, as arrays, lists or stacks.
   

2. The same for this interface:
   
   interface INode
   {
            INode Next { get; }
            object Data { get; set; }
   }
   
   
3. And the same for this:
   
   interface INode
   {
            INode Next { get; }
            object Data { get; }
   }

First and second tasks are almost the same, the 3rd solution will be good for 1st and 2nd as well.
