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>
using namespace std;
int c;
int main() {
	int x, y;
	cin >> x >> y;
	if (x == y && x == 2) {
		cout << "Yes" << endl;
	}
	else if ((x == 4 || x == 6 || x == 9 || x == 11) && (y == 4 || y == 6 || y == 9 || y == 11)) {
		cout << "Yes" << endl;
	}
	else if ((x == 1 || x == 3 || x == 5 || x == 7 || x == 8 || x == 10 || x == 12) && (y == 1 || y == 3 || y == 5 || y == 7 || y == 8 || y == 10 || y == 12)) {
		cout << "Yes" << endl;
	}
	else cout << "No" << endl;
}
