Re: Numeric sorting WITHOUT <=>

[jandrew]

I think an insertion sort using splice might work

Homework Spoiler -

use Modern::Perl;
use Smart::Comments;
my %jetsons = (
    7  => 'Judy',
    10 => 'Jane',
    11 => 'George',
    2  => 'Elroy',
    100=> 'Rosey',
    1  => 'Astro',
    19 => 'Mr. Spacely',
    22 => 'Mr. Cogswell');


my    @result = ();
for my $key ( keys %jetsons ){
    my $x = 0;
    CHECKLIST: for my $value ( @result ){
        if( $value > $key ){
            last CHECKLIST;
        }else{
            $x++;
        }
    }
    splice( @result, $x, 0, $key );
}

### @result

Returns

### @result: [
###            1,
###            2,
###            7,
###            10,
###            11,
###            19,
###            22,
###            100
###          ]
