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

#include <stdio.h>

int main() {
  int x,y = 0;
  int i = 0;
  int Xa,Xb,Xc = 0;
  int Ya,Yb,Yc = 0;
  long a[] = {1,3,5,7,8,10,12};
  long b[] = {4,6,9,11};
  long c[] = {2};

  scanf("%d""%d",&x,&y);
  
  for(i=0;i<7;i++) {
    if(a[i]==x) {
      Xa = 1;
    }
    if(a[i]==y) {
      Ya = 1;
    }
  }
  
  for(i=0;i<4;i++) {
    if(b[i]==x) {
      Xb = 1;
    }
    if(b[i]==y) {
      Yb = 1;
    }
  }

    Xc = 1;
  }
