Given a string s, return a new string with its characters in reverse order. Implement a function that takes a string as input and produces the reversed string as output.
Example 1:
Input: s = "hello"
Output: "olleh"
Explanation: Reversing the character order of "hello" gives "olleh".
Example 2:
Input: s = "racecar"
Output: "racecar"
Explanation: The string is a palindrome, so reversing it produces the same string.
0 <= len(s) <= 10^5s contains printable ASCII characters
