Reverse a Python String Recursively

EasyPython

Problem

How would you reverse a Python string using recursion?

Implement reverse_string(s) so it returns the characters of s in reverse order without using Python's built-in reverse operations. The input is a string, and the output must be a string. Preserve spaces, punctuation, casing, and Unicode characters.

Constraints

0 <= len(s) <= 10^4
s contains valid Python Unicode characters
Do not use reversed(), slicing with a step of -1, or an iterative loop to perform the reversal

Function Signature

def reverse_string(s):
