class MyCode {
    public static void main(String[] args) {
        String input = "Name is the best IT company!";
        System.out.println(reverseWordChars(input));
        System.out.println("!/ynapmoc TI tseb eht si emaN".equals(reverseWordChars(input)));

    public static String reverseWordChars(String str) {
        return new StringBuilder(str).reverse().toString();
    }
