One for the IT employers - where to get test resources from?

[Z064life]

Having had an interview today for a technical consultant role, part of the interview involved a test on programming logic.

I've got the book programming interviews but are there any other books or free internet resources that can really focus on programming logic?

Some of the questions were converting roman numerals into normal figures, wriing code to count the difference between days, and so forth.

Thanks
