If your list is rather small, say N < 20, then I would suggest you use
something along the
lines of your first implementation. If your list is extremely big and
performance matters, then
I suggest you look for another data structure. With a list there is
only so much you can do: You
have to dig into the list in order to get to the Nth element and that
will cost you O(n).
