        We define the usage of capitals in a word to be right when one of the following cases holds:
        </br>
        All letters in this word are capitals, like "USA".
        </br>
        All letters in this word are not capitals, like "leetcode".
        </br>
        Only the first letter in this word is capital, like "Google".
        </br>
        Given a string word, return true if the usage of capitals in it is right.

        Example 1:

        Example 2:

        Input: word = "FlaG"
        Output: false
