        char[] charArray = s.toCharArray();
        int i = 0, j = charArray.length - 1;
        for ( i = 0; i < j; i++, j--){
            char temp = charArray[i];
            charArray[i] = charArray[j];
            charArray[j] = temp;
        }
        
        // s = String.valueOf(charArray);
        return String.valueOf(charArray);
