Reverse String In Place

Problem

Given a string s, write a function that returns the reversed version of the string. The input is a Python string and the output should also be a string. Solve it using a two-pointer technique rather than relying only on built-in reversing shortcuts.

Constraints

• 0 <= len(s) <= 10^5
• s may contain letters, digits, spaces, and punctuation
• The function should return a new reversed string
