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,kx,ky;
int main () {
	cin >> x >> y;
	if (x==2){
		kx=1;
	} else if ((x==4) || (x==6) || (x==9) || (x==11)){
		kx=2;
	} else {
		kx=3;
	}
	if (y==2) {
		ky=1;
	} else if ((y==4) || (y==6) || (y==9) || (y==11)){
		ky=2;
	} else {
		ky=3;
	}
	if (kx==ky){
		cout << "Yes" << endl;
	} else {
		cout << "No" << endl;
	}
}
