in thread Removal of duplicated element in array.

my %seen = map {$_=>1} <DATA>; use Data::Dumper; print Dumper \%seen; __DATA__ dddd@fgg.com cccc@fgg.com eeee@fgg.com dddd@fgg.com
*UPDATE:
If you care about the order of display then you can use this:
  print join "\n", sort{$a cmp $b} keys %seen;

*Note: That was based on the assumption, that the original ORDER of data was inconsequential.
Limbic~Region Thanks for pointing that out.

    2teez,
    If you care about the order of display then you can use this

    The code in the OP looked like it was preserving the original order - what you have posted loses that ordering and sorting ASCIIbetically after the fact isn't going to re-instate it unless it coincidentally was sorted that way in the first place.

    Cheers - L~R

      You are right. My post was on the assumption that, the OP wanted the output in 'ASCIIbetically', hence, the reason for my assertion. Thanks.
