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 main() {
	int x, y;	cin >> x >> y;
	int groupX = 0, groupY = 0;

	if (x == 2) {
		groupX = 3;
	}
	else if (x == 4 || x == 6 || x == 9 || x == 11) {
		groupX = 2;
	}
	else {
		groupX = 1;
	}

	if (y == 2) {
		groupY = 3;
	}
	else if (y == 4 || y == 6 || y == 9 || y == 11) {
		groupY = 2;
	}
	else {
		groupY = 1;
	}

	if (groupX == groupY) {
		cout << "Yes" << endl;
		return 0;
	}
	cout << "No" << endl;

	return 0;
}
