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 main(){
    set<int> a;
    set<int> b;
    set<int> c;
    a.insert(1);
    c.insert(2);
    a.insert(3);
    b.insert(4);
    a.insert(5);
    b.insert(6);
    a.insert(7);
    a.insert(8);
    b.insert(9);
    a.insert(10);
    b.insert(11);
    a.insert(12);
    int x, y;
    cin >> x >> y;
    if(a.count(x) == a.count(y) && b.count(x) == b.count(y) && c.count(x) == c.count(y))
    cout << "Yes" << endl;
    else 
    cout << "No" << endl;
    return 0;
}
