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

Solution in Lua (5.3.2) (judge verdict: Wrong Answer)

local A,B = io.read("*n","*n")
--local function test(A,B)
    --local newMin = math.min(A,B)
    --local newMax = math.max(A,B)
    --for i=newMin,newMax do
        if A*B %2 == 1 then
            print("YES")
        else
            print("NO")
        end
