Correctly Capitalized String Check

Given a string S, determine whether each word in the string is correctly capitalized according to the Royal Typographic Society's guidelines. A word is considered correctly capitalized if it meets one of the following conditions:

• The word is composed entirely of uppercase letters, or
• Only the first letter is uppercase and all subsequent letters are lowercase.

For example, Hello World and HELLO WORLD are correctly capitalized, while Hello world is not.

Note: The evaluation should be made on a per-word basis.

inputFormat

The input consists of a single line containing the string S. The string may include multiple words separated by spaces.

Output True if the string S follows the capitalization rules, otherwise output False. The output should be printed on stdout.
