Good afternoon Monks of Wisdom, I am struggling with a piece of coding that is required for my school assignment. The assignment is set to count the number of characters as well as unique characters. If I entered in - Perl Monks Rocks!!! I should get 19 characters total with 3 unique characters. I have no clue as to how to find the unique characters. This is what I have thus far, and any help is greatly appreciated. 
print "Enter an input string: ";
chomp (my $str = <STDIN>);
print "Input String: $str\n";
my $cnt = @{[$str =~ /./sg]};
print "Total characters (including spaces & punctuation): $cnt\n";
print "Unique Characters (including spaces & punctuation): \n";
