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 <bits/stdc++.h>
using namespace std;
int x,y,gx,gy;
int main () {
cin >> x >> y;
if (x==2) {
	gx=1; 
} else if(x==4||x==6||x==9||x==11) {
	gx=2;
} else {
	gx=3;
}
if (y==2) {
	gy=1;
} else if (y==4||y==6||y==9||y==11) {
	gy=2;
} else {
	gy=3;
}
if (gx==gy) {
	cout << "Yes" << endl;
} else {
	cout << "No" << endl;
}
}
