+https://leetcode.com/problems/detect-capital/
+Given a word, you need to judge whether the usage of capitals in it is right or not.
+
+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".
+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
