I'd be OK with restricting the input to only valid BCD as getting the other cases right isn't really much fun and restricts the possible implementations.

Hi paraj, the same work is the same work
(I did somersaults to consider illegal cases too
)
Why resticts the implementations? I think it amplifies them..
