Re: splitting array values

[bobn]

Show us all the code startng with creation of the array and ending with the sort.

[mkurtis]

the code that creates the array looks like this

while( ($key, $value) = each %rank ) {
    $rank = $rank . " " . $key;
    }
    push @rank, split(/\s/, $rank);
        @rank2=sort { $b <=> $a } @rank;
    foreach my $rank2 (@rank2) {
    print $rank2 . "\n";
    print "$rank2\n\n" . $rank{"$rank2"} . "\n\n";
    }

I think this is what you wanted. Thanks for the help so far.

Is there another way to sort things. For example could I take each key from the hash and compare it to all the others until I found the largest and then so on? I'm not quite sure how this would be done, but I can't get sort to work, or reverse either, it's like all the numbers are in array element and won't seperate, even though I can join them with letters in between.

Thanks

Okay, when I use Data::Dumper it prints

$VAR1 = [
          '12'
        ];

For all of them, the number changes but it always says $VAR1, I've never used Data::Dumper before but I don't think thats a good thing.

Thanks

You seem to be doing a lot of work for something quite simple:

my @ranks = sort { $b <=> $a } keys %rank;
for my $r (@ranks) {
   print "$r $rank{$r}\n";
}

Why join all of the keys together with a space, then split them apart again?

[mkurtis]

Thats what I though duff, but your code doesn't sort them, for some reason they stay in the same order and I don't know why.

Thanks

Podmaster, Heres whats happening. Ive got a scalar full of number values, some negative. It is stored in $sorted. From there the code goes like this

foreach my $sorted(@sorted){
    $scorehash{$sorted} = undef;
    }
    print Dumper(%scorehash);
    my @ranks2 = sort { $b <=> $a } keys %scorehash;
    print Dumper(\@ranks2);
    print $ranks2[0];

the output is all the values not in order for both printings. Thanks

Okay, I get these keys from the hash:
When printed with Data Dumper they look like this:

$VAR1 = [
          '-12'
        ];
$VAR1 = [
          '7'
        ];
$VAR1 = [
          '26'
        ];
$VAR1 = [
          '-123'
        ];
$VAR1 = [
          '7'
        ];
$VAR1 = [
          '39'
        ];
$VAR1 = [
          '30'
        ];
$VAR1 = [
          '32'
        ];
$VAR1 = [
          '-504'
        ];
$VAR1 = [
          '-12'
        ];
$VAR1 = [
          '150'
        ];

They are always in that order, even when I sort them, reverse them ...

I think this is what you want
