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,book[12];
    scanf("%d%d",&x,&y);
	if(x==2)
		book[x]=3;
	else if(x==4||x==6||x==9||x==11)
		book[x]=2;
	else
		book[x]=1;
	if(y==2)
		book[y]=3;
	else if(y==4||y==6||y==9||y==11)
		book[y]=2;
	else
		book[y]=1;
	if(book[x]==book[y])
		printf("Yes");
	else
		printf("No");
	return 0;
}
