Reverse A String Recursively

Complete reverse_string(s: str) -> str so it returns the text reversed, by recursion and without the [::-1] slice. The base case is written: the empty string reverses to the empty string. Add the recursive case, which returns the reversed tail s[1:] followed by the first character s[0]. Do NOT write a main block or any top-level test code; the tests construct the calls. Input: one line of text, no prompt, which the tests read and pass to your function before printing the string it returns (an empty line reverses to an empty line).
