Given a word, you need to judge whether the usage of capitals in it is right or not.

Otherwise, we define that this word doesn‘t use capitals in a right way.
Example 1:
Input: "USA" Output: True
Example 2:
Input: "FlaG" Output: False
Note: The input will be a non-empty word consisting of uppercase and lowercase latin letters.
