I am trying to understand this sort and uniq code that a came across in
the archive. This works, but I thought the %uniq would have the sort
and uniqed values. What is needed if I didn't want to print the values
out immediatedly but put them in an array or hash?
#!/usr/bin/perl
use strict;
use warnings;
my @holdArr =qw(apple pear lemon bananna apple pear);
my %uniq;
map{$uniq{$_}=1 and print "$_\n" unless $uniq{$_}
