Data Dumper guidance

[Kasp]

Hi Everyone,

Need some help in Data:umper.
What I want to do is sort this array (@arr) based on the first element of
the sub-arrays.
So I want finally is @sarr = ([3,2], [5,0], [6,3]);

Here is the code:
use Data:umper;
my @arr = ([5,0], [3,2], [6,3]);
print Data:umper->Dump(\@arr);
my @sarr = sort { $a <=> $b} @arr;
print Data:umper->Dump(\@sarr);

TIA

So, really this has nothing to do with Data:umper, but with
sorting.

Here is the code:
use Data:umper;
my @arr = ([5,0], [3,2], [6,3]);
print Data:umper->Dump(\@arr);
my @sarr = sort { $a <=> $b} @arr;

That will sort on the array references in @arr.

You want this:
my @sarr = sort { $a->[0] <=> $b->[0]} @arr;

You want this:

my @sarr = sort { $a->[0] <=> $b->[0]} @arr;

Thanks Andreas.
