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

package main

import (
	"bufio"
	"os"
	"strings"
	"strconv"
)

func main() {
	stdin := bufio.NewScanner(os.Stdin)
	stdin.Scan()
	text := stdin.Text()
	strs := strings.Fields(text)
	a, err := strconv.Atoi(strs[0])
	if err != nil {
		panic(err)
	}
	b, err := strconv.Atoi(strs[1])
	if err != nil {
		panic(err)
	}
	result := a * b
	if result % 2 == 1 || (result * 3) % 2 == 1 {
		print("Yes")
	} else {
		print("No")
	}
