>> Economizei mais performance:
>> sub is_ordered {
>>     my $a = shift;
>>     my $numta = 1;
>>     for ( my $i = 1 ; $i < @{$a} ; $i++ ) {
>>         $numta = 0 if ( $a->[ $i - 1 ] > $a->[$i] && $numta == 1);
>>     }
>>     return 0 if !$numta;
>>     return 1 if $numta;
>>     return undef if (!$numta || $numta); # muito importante
>> }
