I feel foolish

The method returns an int, and Math.Ceiling returns a double, you'll need to convert them into int.

Now I look on it, You Right .Thank You

lol

ggggg

This is an odd way to approach the boolean expression. If you ever find your self checking a coniditon, only to output a boolean, then there's likely something odd going on.

dang fr? can you say which 6 kata were easy? i can complete 8s easily and 7s kinda, but 6s are really hard for me

Your function/method checks whether the input string is all lowercase while this Kata asks you to check whether the string is all uppercase.

I learned something day. We dont always have to explictly state the return type. We can state Object
:D
great KATA

I think this should be a 7 Kata. I've done 6 kata easier than this. IMO

char? is independent on Tuple. The ? makes the char nullable i.e. you can assign null to it which you can't do with a normal char (see. e.g. this).
