I have an array of numbers and an array of strings: 
@numbers = ('1','1','1','2','2','3','3','4','4','5','6');
@strings = ('hello','you','tree','people','fun','sun','grass','love','
+food','car','rabbit');

Both arrays have the same number of elements in them. I basically want to concatenate the strings together if the numbers in @numbers are the same. e.g. if $number$i is 1, concatenate all of the correponding elements from @strings together: So would end up with the following new strings: 
helloyoutree
peoplefun
sungrass
lovefood
car
rabbit

My code fails for the last consecutive same number in a row! Can anyone see what i'm doing wrong? Many many thanks ! 

for (my $i=0; $i< @numbers; $i++)    {
   if (($numbers[$i] == $numbers[$i+1]) || ($numbers[$i] == $numbers[$
+i-1]))     {
                                                                      
+                                                                     
+                                   

              
                push @new_array, "$strings[$i]";
     }
                                                                      
+                                                                     
+                                   
     else {
              push @new_array, ">";
               push @new_array, $strings[$i];
               push @new_array, ">";
              
    }
}
my $j = join ('', @new_array);
$j =~ s/\s+//;
@new_array = split (/>+/, $j);
