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() {

    int x, y;
    int a1 = 0, b2 = 0, c3 = 0;
    int a[7] = {1,3,5,7,8,10,12};
    int b[4] = {4,6,9,11};
    int c[1] = {2};

    cin >> x >> y;
    for (int i = 0; i < 7; i++) {
        if (x == a[i] || y == a[i]) a1++;
        else;
    }
    

    for (int i = 0; i < 4; i++) {
        if (x == b[i] || y == b[i]) b2++;
        else;
    }
    

    for (int i = 0; i < 1; i++) {
        if (x == c[i] || y == c[i]) c3++;
        else;
    }
    

    if (a1 == 2 || b2 == 2 || c3 == 2) {
        cout << "Yes" << endl;
    }
    else
        cout << "No" << endl;
