Reverse AlphaSense Query String | Dataford Interview Questions

In AlphaSense, query text entered in search surfaces may need simple string transformations during client-side processing. Write a function that takes a string s and returns a new string with its characters in reverse order.

Formal Specification

Input: a string s
Output: a string containing the characters of s in reverse order
Your function should preserve all characters exactly as they appear, including spaces, punctuation, digits, and letter casing.

Notes

Return the reversed string.
Do not remove or modify any characters.
Aim for a linear-time solution.
In Python, strings are immutable, so an efficient solution typically converts the string to a list, swaps characters with two pointers, and joins the result.

Constraints

0 <= len(s) <= 10^5
s may contain letters, digits, spaces, and punctuation
Return a new reversed string without removing any characters

Function Signature

def reverse_string(s):
