in reply to Subroutine Even/Odd

Here's what I came up with.

#!/usr/bin/perl use strict; use warnings; sub num { my $array = shift; my $func = shift; return grep {$_%2==0} @$array if ($func eq 'even'); return grep {$_%2!=0} @$array if ($func eq 'odd'); } my @a = 1..10; my @b = (447..460, 2000..2012); print num(\@a, 'even'), "\n"; print num(\@b, 'odd'), "\n";
I'm a beginner so please inform me if this is an inefficient/misguided way of accomplishing this.
