Problem Statement

Based on some criterion, Snuke divided the integers from 1 through 12 into three groups as shown in the figure below.
Given two integers x and y (1 ≤ x < y ≤ 12), determine whether they belong to the same group.

Constraints

x and y are integers.

1 ≤ x < y ≤ 12

Input

Input is given from Standard Input in the following format:

x y

Output

If x and y belong to the same group, print Yes; otherwise, print No.

Sample Input 1

1 3

Sample Output 1

Yes

Sample Input 2

2 4

Sample Output 2

No

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
#include <string.h>

int main(void)
{
    int a,a1;
    scanf("%d %d",&a,&a1);
    if(a==1||a==3||a==5||a==7||a==8||a==10||a==12) a=1;
    else if(a==2) a=2;
    else a=3;
    if(a1==1||a1==3||a1==5||a1==7||a1==8||a1==10||a1==12) a1=1;
    else if(a1==2) a1=2;
    else a1=3;
    if(a==a1) printf("Yes");
    else printf("No");
    return 0;
}
