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 a[12] = {1,3,5,7,8,10,12,4,6,9,11,2};
	int x,y,i,b,c;
	scanf("%d %d",&x,&y);
	for(i = 0;i < 12;i++)
	{
		if(x == a[i])
			b = i;
		if(y == a[i])
			c = i;
	}
	if((b >= 0 && b <= 6) && (c >= 0 && c <= 6))
		printf("Yes\n");
	else if((b >= 7 && b <= 10) && (c >= 7 && c <= 10))
		printf("Yes\n");
	else
		printf("No\n");
	return 0;
}
