Re^2: Unique Character

Thanks for pointing that out to me ww about the unique characters. I used my phone a friend, and they explained to me what my professor wants. The unique characters he wants is how often a character is repeated. Such as if I used Jim Doe. There would be a total of 8 unique characters. If I used John Doe. there would still be 8 unique characters due to the o was already counted.

This will do the trick: `use Modern::Perl; my $string = "Perl Monks Rocks!!!"; my %chars; for ( split '', $string ) { $chars{ lc $_ }++ } my @uniques = sort keys %chars; say scalar @uniques, ": @uniques";` [download] CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James My blog: Imperial Deltronics	[reply] [d/l]

use Modern::Perl;

my $string = "Perl Monks Rocks!!!";
my %chars;

for ( split '', $string ) { $chars{ lc $_ }++ }

my @uniques = sort keys %chars;

say scalar @uniques, ": @uniques";
