Description

You are given integers $A$ and $B$, each between $1$ and $3$ (inclusive).

Determine if there is an integer $C$ between $1$ and $3$ (inclusive) such that $A \times B \times C$ is an odd number.

Input

Input is given from Standard Input in the following format:

```
$A$ $B$
```

Output

If there is an integer $C$ between $1$ and $3$ that satisfies the condition, print `Yes`; otherwise, print `No`.

Constraints

-   All values in input are integers.
-   $1 \leq A, B \leq 3$

Sample 1 Input
