Description
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"
