Alice was stuck in the middle of the Mini Comp! Therefore, she wanted to try the powerful AI, Gemini. However, she was scrolling through the App Store too fast without her glasses and accidentally downloaded Gemimi.

Unfortunately, Gemimi is completely useless. Whenever a user submits a prompt, Gemimi always answers in the following format:
As an AI language model, I do not know {…}.

Write a program that reads Alice’s prompt and simulates the exact responses generated by the Gemimi application.

Input

The input contains a single string $S$.

Output

Output in the following format:
As an AI language model, I do not know $S$.
(Note that there is no space between S and .)

Subtasks

For all cases, $1 \le |S| \le 1000$, where $|S|$ denotes the length of the string.
$S$ only contains lowercase alphabet letters and spaces.
$S$ does not begin or end with a space.

Subtask 1 (30 pts): $S$ = “how to code dijkstra”
Subtask 2 (30 pts): $S$ only contains lowercase alphabet letters
Subtask 3 (40 pts): No additional constraints
