in reply to Removal of duplicated element in array.

Hi tty1x,
A few snapshot observations and 2 'kobo' suggestion:

  • A number of solution previously given to you actually work, only that some may not preserve the order of data.
  • This does work for me, which is not far from your OP, except that I have to create the variable $match.
    use warnings; use strict; my $match = <<'EOF'; dddd@fgg.com cccc@fgg.com eeee@fgg.com dddd@fgg.com EOF my %seen; my @r; foreach my $v ( split /\n/, $match ) { unless ( $seen{$v}++ ) { push @r, $v; } } $" = "\n"; print "@r";
  • Please, as much as possible try not to use the variable $a, since function sort uses it
Tested this out on codepad an online compiler/interpreter.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

    Perl 5.8.0? What a pitty :-(

      Yeap! I know. When the OP kept complaining about virtually all the solution given and he/she said he/she is using v5.10.1.
      I thought if the solution am presenting works on a version as old as v5.8.0, then it should work on v5.10.1. That was why I mentioned that.

      If you show me, I'll remember.
      if you involve me, I'll understand.
