in reply to a close prime number

That's really easy:

sub find_closest_primes { my $number = shift; my @close_primes; for my $close (find_close_numbers( $number )) { push @close_primes, $close if is_prime( $close ); } return @close_primes; }

All you have to do is fill in the behavior of find_close_numbers() and is_prime()!

    Your solution reminds me of me of a article currently referenced from the Joel on Software homepage, which talks about the the do-magic-here step.

    :)

      I don't necessarily think of it as magic; I didn't know what the supplicant would consider a "close" number nor did I know which prime number finding algorithm he might find acceptable.

      It's not really a joke answer. It's how I would divide the problem if I were doing it.
