In the annual Syrian Collegiate Programming Contest for Private Universities, there's a running joke among teams: the first problem — affectionately called "The Extreme" — is supposed to be the easiest one in the entire contest.

Before the contest begins, coaches often tease the teams with the same iconic question:

"What'll You Do If You Didn't Solve The Extreme?"

The question is always asked exactly this way — with the same wording, the same capitalization, and yes... even the question mark at the end.

If a participant hears this question and responds with:

"I Guess We'll Never Know"

— they're officially forgiven.

Your task is to write a program that reads the exact question from the input and responds with the standard answer.

Input

A single line containing a string represents the question.

Output

You have to out put the phrase "I Guess We'll Never Know" exactly as it is (no extra spaces and the same cases).

Example
Input
What'll You Do If You Didn't Solve The Extreme?
Output
I Guess We'll Never Know
