Given two scalars that contain non-negative integer values, as ($numerator, $denominator). $denominator is non-zero as well.

Find the perl golf solution subroutine that returns the reduced fraction; that is, a fraction that is still equivalent to the initial fraction but using the smaller possible (non-negative!) integer values to make it up. The fraction is returned as an array in the order of (numerator, denominator).

Examples can include: 
@a = reduce( 512, 1024 );  # @a = ( 1, 2 )
@a = reduce( 12, 18 );     # @a = ( 2, 3 )
@a = reduce( 1, 7 );       # @a = ( 1, 7 )
