    344 - Reverse String.

    Easy

    Write a function that reverses a string. The input string is given as an array of characters s.

    Example 1:

    Input: s = "h","e","l","l","o"

    Output: "o","l","l","e","h"

    Example 2:

    Input: s = "H","a","n","n","a","h"

    Output: "h","a","n","n","a","H"
