+# 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 if it has more than one letter, 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
+# Note: The input will be a non-empty word consisting of uppercase and lowercase latin letters.
