+To find the answer, you can consult the book section "References and Borrowing":
+https://doc.rust-lang.org/stable/book/ch04-02-references-and-borrowing.html
+The first problem is that `get_char` is taking ownership of the string.
+So `data` is moved and can't be used for `string_uppercase`
+`data` is moved to `get_char` first, meaning that `string_uppercase` cannot manipulate the data.
+Once you've fixed that, `string_uppercase`'s function signature will also need to be adjusted.
+Can you figure out how?
+
+Another hint: it has to do with the `&` character."""
