I want to compare the elements of the first row with the corresponding elements of the second row, and if the first 2 sets matches i want to display

a
b

following is my code 

my arr_ref= $sth->fetchall_arrayref();
foreach my $row(@$arr_ref) {
   #missing something here
    my ($ele1,$ele2,$ele3)= @$row;
    print "$ele1\t",
    print "$ele2\t",
    print "$ele3\n",
}
