Hi ,

The function get_pairs has to be written this way . The previous node has to be ignored as the usage of map is not so much appropriate , though we get the solution as required by that 

         use Data::Dumper;
         
         my @seg1 = ("one","two","three");

         my @seg2 = ("four","five");

         #create references 

         my $seg1 = \@seg1;
         my $seg2 = \@seg2;
         my $seg3 = \@seg3;
         my $seg4 = \@seg4;
         my $seg5 = \@seg5;

         my @pairs = get_pairs($seg1,$seg2,$seg3,$seg4,$seg5);

        print Dumper \@pairs;

        sub get_pairs {

            my @seg_pairs = @_; 
            my @pairs = map {
                          local $arr_frst_scalar = $_;
                          map {
                            ["$arr_frst_scalar->[$_-1] $arr_frst_scala
+r->[$_]"] ;
                          }1..scalar(@$_)
                        }@seg_pairs; 

            return @pairs; 

         }

__END__

$VAR1 = [
          [
            'one two'
          ],
          [
            'two three'
          ],
          [
            'three'
          ],
          [
            'four five'
          ],
          [
            'five'
          ]
