Problem Statement

Takahashi has forgotten his PIN. The PIN is a four-digit string consisting of 0, 1, $\\ldots$, 9, and may begin with a 0.

For each digit 0 through 9, Takahashi remembers the following fact, represented by a $10$-character string $S_0S_1 \\ldots S_9$:

• if $S_i$ is o: he is certain that the PIN contained the digit $i$;
• if $S_i$ is x: he is certain that the PIN did not contain the digit $i$;
• if $S_i$ is ?: he is not sure whether the PIN contained the digit $i$.

How many strings are there that could be Takahashi's PIN?

Constraints

• $S$ is a $10$-character string consisting of o, x, and ?.
