Problem 117: Incitatus

(U.M. ACM Runoffs 2003, problem 4)

Description

President Dubya has appointed his favourite horse, Francis, to the Supreme Court. Now Francis has to be confirmed by the senate, and in order to succeed, he must impress the senators with his answers to their questions.

Fortunately, in the tradition of trained horses, Francis can perform simple arithmetical operations and indicate the answer by stamping his foot the right number of times. Each stamp of his foot produces a "clop" sound, so if a senator asks Francis "what is two plus two", the response will be "clop clop clop clop". Francis has been taught to respond with a "Neigh!" to questions he can not answer.

The senators are permitted to ask Francis questions in any of these three forms:
          What is A and B
          What is A plus B
          What are A and B
where A and B may be replaced by any of the words
          One, Two, Three, Four, Five, Six, Seven, Eight, or Nine.

If the question asked by a senator exactly matches one of the allowed forms, the response must be the right number of clops, each separated from the next by a space, and terminated by a full-stop or period. If the question does not exactly match one of those forms, the response must be "Neigh!". You must write a program that predicts exactly what Fracis will "say" for any given question.

Input Format

The input will be a sequence of questions, each occupying a whole single line. Each line of input represents a separate question. The input is not case sensitive, and words may be preceeded or followed by any number of spaces, but there will be no additional characters in a correct question. The end of the input is marked by a line beginning with the word "stop", which should not be responded to.

Output Format

For each line of input (except the "stop" line) produce exactly one line of output. If the input matches a valid form of question, the output must be the correct number of "clop"s separated by single spaces and terminated with a full stop. If the input does not match a valid form, the output should be the word "Neigh!" eactly as shown, with capital N and exclamation mark.

Limits

No input line will exceed 1000 characters in length.
