Recursive String Reversal | Dataford Interview Questions

Reverse a string using recursion.

Implement reverse_string(s) to return a new string containing the characters of s in reverse order. Use recursive calls as the primary technique, preserve spaces and special characters, and do not use the built-in reverse or slicing-based reversal.

Function: reverse_string(s)

Input: a string. Output: its reversed string.

Constraints

0 <= len(s) <= 1000
s may contain letters, digits, spaces, and special characters
The result must preserve every input character exactly once
Use recursion for the reversal logic
Do not use built-in reversal functions or slicing-based reversal

Function Signature
