520 - Detect Capital\. Easy We define the usage of capitals in a word to be right when one of the following cases holds: * All letters in this word are capitals, like `"USA"`. * All letters in this word are not capitals, like `"leetcode"`. * Only the first letter in this word is capital, like `"Google"`. Given a string `word`, return `true` if the usage of capitals in it is right. **Example 1:** **Input:** word = "USA" **Output:** true **Example 2:** **Input:** word = "FlaG" **Output:** false **Constraints:** * `1 <= word.length <= 100` * `word` consists of lowercase and uppercase English letters.
