Question

What is the name for the sort used in this answer? I Googled for “perfect insertion sort” but didn’t find anything. Here is the code from that answer:

#this is O(n) instead of O(n log n) or worse
sub perfect_insert_sort {
    my $h = shift;
    my @k;
    for my $k (keys %$h) {
        $k[$h->{$k}{order}] = $k;
    }
    return @k;
}

I think I probably should have named that perfect_bucket_sort instead of perfect_insertion_sort.
