Why don't you use a hash to concatenate, with numbers as keys? Something like:
use strict;
use warnings;
use Data::Dumper;
my @numbers = ('1','1','1','2','2','3','3','4','4','5','6');
my @strings = ('hello','you','tree','people','fun',
'sun','grass','love','food','car','rabbit');
my %hash;
for (0..$#numbers){
$hash{$numbers[$_]} .= $strings[$_];
}
print Dumper(\%hash);
__OUTPUT__
$VAR1 = {
'6' => 'rabbit',
'4' => 'lovefood',
'1' => 'helloyoutree',
'3' => 'sungrass',
'2' => 'peoplefun',
'5' => 'car'
};
You can also use an array instead of a hash.
