Allen is playing Number Clicker on his phone.

He starts with an integer $u$ on the screen. Every second, he can press one of 3 buttons.

1. Turn $u \to u+1 \pmod{p}$.
2. Turn $u \to u+p-1 \pmod{p}$.
3. Turn $u \to u^{p-2} \pmod{p}$.

Allen wants to press at most 200 buttons and end up with $v$ on the screen. Help him!

Input

The first line of the input contains 3 positive integers: $u, v, p$ ($0 \le u, v \le p-1$, $3 \le p \le 10^9 + 9$). $p$ is guaranteed to be prime.

Output

On the first line, print a single integer $\ell$, the number of button presses. On the second line, print integers $c_1, \dots, c_\ell$, the button presses. For $1 \le i \le \ell$, $1 \le c_i \le 3$.

We can show that the answer always exists.
