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>
#include<string.h>
int main(void) {
	// your code goes here
int a,b,i,flag,k;
scanf("%d%d",&a,&b);
flag=0;
i=(a>b)?b:a;
k=(a>b)?a:b;
for(i;i<=k;i++)
{
if((i*a*b)%2!=0)
{
flag=1;
}
}
if(flag==1)
{
printf("Yes");

}else{
printf("No");
}
return 0;
}
