letter in text will not return count. It will just return true or false.

So use filter to count character like this:

fun letter_count(letter: Char, text: String): Int {

return text.filter { it == letter }.count()
}

Here it means iterator which will read each character and will compare with passed character.

I know that boolennot needed here just didn't know what else to write. But your version looks very new and since you wrote, we have not learned yet
