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