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
