翻译中…
Given are a prime number $P$ and positive integers $a$ and $b$. Determine whether there is a sequence of $P$ integers, $A = (A_1, A_2, \ldots, A_P)$, satisfying all of the conditions below, and print one such sequence if it exists.

$1\leq A_i\leq P - 1$.$A_1 = A_P = 1$.$(A_1, A_2, \ldots, A_{P-1})$is a permutation of$(1, 2, \ldots, P-1)$.- For every
$2\leq i\leq P$, at least one of the following holds. $A_{i} \equiv aA_{i-1}\pmod{P}$$A_{i-1} \equiv aA_{i}\pmod{P}$$A_{i} \equiv bA_{i-1}\pmod{P}$$A_{i-1} \equiv bA_{i}\pmod{P}$

样例
Input #1
13 4 5
Output #1
Yes
1 5 11 3 12 9 7 4 6 8 2 10 1
This sequence satisfies the conditions, since we have the following modulo $P = 13$:
- $A_2\equiv 5A_1$
- $A_2\equiv 4A_3$
- $\vdots$
- $A_{13}\equiv 4A_{12}$
Input #2
13 1 2
Output #2
Yes
1 2 4 8 3 6 12 11 9 5 10 7 1
Input #3
13 9 3
Output #3
No
Input #4
13 1 1
Output #4
No
