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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<iostream>
#include<string>
using namespace std;
int main(){
	int x,y,a=1,b=1;
	cin>>x>>y;
	if(x==2)a=2;
	if(x==4||x==6||x==9||x==11)a=3;
	if(y==2)b=2;
	if(y==4||y==6||y==9||y==11)b=3;
	if(a==b)cout<<"Yes"<<endl;
	else cout<<"No"<<endl;
	return 0;
}
