How do I print unique elements in Perl array?
Your best bet would be to use a (basically) built-in tool, like uniq (as described by innaM).
If you don't have the ability to use uniq and want to preserve order, you can use grep to simulate that.
my %seen;my @unique = grep { ! $seen{$_}++ } @faculty;# printing, etc.This first gives you a hash where each key is each entry. Then, you iterate over each element, counting how many of them there are, and adding the first one. (Updated with comments by brian d foy)
