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>

int main() {
  int x, y;
  std::set<int> st1{1, 3, 5, 7, 8, 10, 12};
  std::set<int> st2{4, 6, 9, 11};
  scanf("%d %d", &x, &y);
  if (x == 2 || y == 2) {
    printf("No");
  } else if (st1.count(x) != 0 && st1.count(y) != 0 ||
             st2.count(x) && st2.count(y) != 0) {
    printf("Yes");
  } else {
    printf("No");
  }
}
