Reverse String Without Libraries | Dataford Interview Questions

Write a program to reverse a string without using built-in library functions.

Constraints

0 <= len(s) <= 1000
s may contain letters, digits, spaces, punctuation, and Unicode characters
The input string must not be modified

Function Signature
