        String str = "Let's take LeetCode contest";
        String reverseWords = reverseWords(str);
        System.out.println("reverseWords = " + reverseWords);
    }

    public static String reverseWords(String s) {
        if (s == null || s.length() == 0) {
            return s;
        }
        String[] strings = s.split(" ");
        StringBuilder stringBuilder = new StringBuilder(s.length());
        for (String s1 : strings
        ) {
            StringBuilder t = new StringBuilder();
            t.append(s1);
            stringBuilder.append(t.reverse().toString());
            stringBuilder.append(" ");
        }
