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: Wrong Answer)

#include<iostream>
using namespace std;

int main(){
	int x,y;
	int x1,y1,a[]={4,6,9,11},b[]={1,3,5,7,8,10,12}; 
	cin >> x >> y;

	if(x==2||y==2||x==11||x==12){
		cout << "No" << endl;
		return 0;
	}
	for(int i=0;i<4;i++){
		if(x==a[i]){
			x1=2;
			break;
		}
		if(y==a[i]){
			y1=2;
			break;
		}
	}
	for(int i=0;i<7;i++){
		if(x==b[i]){
			x1=1;
			break;
		}
		if(y==b[i]){
			y1=1;
			break;
		}	
	}
	if(x1==y1){
		cout << "Yes" << endl;
		return 0;
	}else{
		cout << "No" << endl;
		return 0;
	}

	return 0;
