+Write a function that reverses a string. The input string is given as an array of characters s.
+
+You must do this by modifying the input array [in-place](https://en.wikipedia.org/wiki/In-place_algorithm) with O(1) extra memory.
+
+Example 1:
+
+> Input: s = ["h","e","l","l","o"]<br>
+> Output: ["o","l","l","e","h"]
+
+Example 2:
+
+> Input: s = ["H","a","n","n","a","h"]<br>
+> Output: ["h","a","n","n","a","H"]
+
+Constraints:
+
+- 1 <= s.length <= 105
+- s[i] is a [printable ascii character](https://en.wikipedia.org/wiki/ASCII#Printable_characters).
