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>
int main()
{
	int x,y;
	scanf("%d %d",&x,&y);
	if(x==2||y==2)
	{
		printf("No\n");
	}
	else if((x==4||x==6||x==9||x==11)&&(y==4||y==6||y==9||y==11))
	{
		printf("Yes\n");
	}
	else if((x==1||x==3||x==5||x==7||x==8||x==10||x==12)&&(y==1||y==3||y==5||y==7||y==8||y==10||y==12))
	{
		printf("Yes\n");
	}
	else 
	{
		printf("No\n");
	}
	return 0;
}
