"Backward"-Iterator - Beginners question

[Ulrich Goebel]

Hallo,

I'm locking for an "iterator" type with not only the .next() method, but
with a .previous(), .first() and .last() method, so that I can through
it from the beginning or from the end, and in both directions, even
alternately (for example two steps forward, one backward, two steps
forward).

Any help will be wellcome!

Simply write a class with these methods. Where is the problem?
