in reply to compare two strings and return only he unique values.

You can also use List::Compare

use List::Compare; my ($str1, $str2) = ("ABCDE", "BCDEO"); my @list1 = split //, $str1; my @list2 = split //, $str2; my @unique = List::Compare->new(\@list1, \@list2) ->get_symmetric_difference; say "Unique letters: @unique";
