Reverse a string without using built-in methods. Implement reverse_string(s) to return a new string containing the characters of s in reverse order. Do not use slicing, reversed(), .reverse(), or other reversal helpers; preserve spaces, punctuation, case, and Unicode characters.

Constraints

0 <= len(s) <= 10^5
s may contain letters, digits, spaces, punctuation, and Unicode characters
Return a new string and do not modify the input
