# 
# 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:
# 
#   1. All letters in this word are capitals, like "USA".
#   2. All letters in this word are not capitals, like "leetcode".
#   3. 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
#     
# 
# 
# 
# **Note:** The input will be a non-empty word consisting of uppercase and
# lowercase latin letters.
