1. Write a function (in Java) 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"]

class Solution

{

public void reverseString(char[] s)

{ //write your answer here.

}

}
