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