Not really. If programmers were just obsessed with taking up as little
space as possible, we wouldn't have whitespace in our code. All the code
would fit in very little space but it would be very, very hard to read
and edit.
Minimising the length of the code isn't everything - readability (and
hence maintainability) counts for a lot.
Others have posted one liners that would do the trick but personally I'd
write it out with ifs for the sake of clarity...
