Reverse String

Write a function that takes a string as input and returns the string reversed.

Example: Given s = "hello", return "olleh".

public class Solution {
    public String reverseString(String s) {
        int left = 0, right = s.length()-1;
        char temp;
        char[] list = s.toCharArray();
        while(left<right){
            temp = list[left];
            list[left] = list[right];
            list[right] = temp;
            left++; right--;
        } 
        return new String(list);
    }
}
