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"
	"fmt"
	"os"
	"strconv"
	"strings"
)

func main() {
	r := bufio.NewReader(os.Stdin)
	s, _ := r.ReadString('\n')
	s = strings.TrimRight(s, " \t\n")
	slice := strings.Split(s, " ")
	a := string(slice[0])
	b := string(slice[1])
	A, _ := strconv.Atoi(a)
	B, _ := strconv.Atoi(b)

	for i := 1; i <= 3; i++ {
		if A*B*i%2 == 1 {
			fmt.Println("Yes")
			os.Exit(0)
		}
	}
	fmt.Println("No")
	os.Exit(0)
