what you did not understand from the above code ? Don't you know exists $is_prime{$_} part checks whether a key exists in a hash or not. Don't you know $is_prime{$_} checks a value with the key in hash is true.(assuming your is_prime() function Boolean value(True or False)) All is well. I learn by answering your questions...
