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 C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main (){
  int a,b,c,i,temp;
  int flag = 0;
  
    
  scanf("%d %d",&a,&b);
  
  for(i = 1;i < 4;i++){
    if(a * b * i % 2 != 0){
      flag = 1;
    }
  }

  if(flag == 1){
    printf("Yes");
  }else{
    printf("No");
  }
    
        return 0;
  
}
