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: Wrong Answer)

#include<stdio.h>
int a[13];
int main ()
{
	int x=0,y=0;
	a[4]=1;a[6]=1;a[9]=1;a[11]=1;a[2]=4;
	scanf("%d%d",&x,&y);
	if(a[x]+a[y]==0||a[x]+a[y]==2)
	printf("YES\n");
	else
	printf("NO");
	return 0;
}
