### Problem Statement

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.

### Constraints

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

### 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.

### Sample Input 1

3 1


### Sample Output 1

Yes


Let $C = 3$. Then, $A \times B \times C = 3 \times 1 \times 3 = 9$, which is an odd number.

### Sample Input 2

1 2


### Sample Output 2

No


### Sample Input 3

2 2


### Sample Output 3

No
