Hi @igraves ,

If you want to test all characters from `A-Z` and `0-9`, consider using `rangeClosed` instead of `range`


Stream<Character> letterChars = IntStream.range('A', 'Z').mapToObj((i) -> (char) i);
Stream<Character> digitChars = IntStream.range('0', '9').mapToObj((i) -> (char) i);

Becomes

Stream<Character> letterChars = IntStream.rangeClosed('A', 'Z').mapToObj((i) -> (char) i);
Stream<Character> digitChars = IntStream.rangeClosed('0', '9').mapToObj((i) -> (char) i);
