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[7] = {1,3,5,7,8,10,12};
  long b[4] = {4,6,9,11};
  long c[1] = {2};

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

      Xc = 1;
    }

      Yc = 1;
    }
  }
