hi

Party of the first part? Smart quotes snuck in your post;)

compare to yours, what did i change?

use strict;
use warnings;
my @input = ( -222, -221, -21, 0, 1,
 1, 2, 3, 5, 8, 13, 21, 
34, 55, 89, 144 );
print $_, " " for oddDigitSum(@input);
print "\n";
exit 0;

sub oddDigitSum {
    my @ans;
    for my $int (@_) {
        my @digits = split //, abs $int;
        my $sum = 0;
        $sum += $_ for @digits;
        $sum % 2 and push @ans, $int;
    }
    return @ans;

compare to yours, and mine, what did i change?

use strict;
use warnings;
my @input = ( -222, -221, -21, 0, 1,
 1, 2, 3, 5, 8, 13, 21,

print $_, " " for oddDigitSum(@input);
print "\n";
exit 0;

sub oddDigitSum {
    my @ans;
    for my $int (@_) {
        my $sum = 0;
        $sum += $_ for split //, abs $int;;
        $sum % 2 and push @ans, $int;
    }

compare to yours, and mine, and mine, what did i change? Is it better? Simpler? Clearer? New and unfamiliar? Ambiguous? Faster?
