someone posted (and it wasn't homework) for an easy way to get all
possible combos of YN (5 chars so 32 answers). he got some basic
multiline answers but i think it makes for a great golf problem.

here is my first pass which i am sure can be easily bested. i haven't
even squeezed out the white spaces but it does work.

golf away!

uri

perl -le 'print join "\n", map {tr/01/NY/; $_} map unpack( "b5", chr), 0 .. 31'
