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 (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main(){
  int group[14]={1,3,5,7,8,10,12,0,4,6,9,11,0,2};
  int x,y;
  int i;
  scanf("%d %d",&x,&y);
  for(i=0;i<14;i++){
    if(group[i]==x){
      break;
    }
  }
  if(i<7){
    for(int j=0;j<7;j++){
      if(group[j]==y){
	printf("Yes");
	return 0;
      }
    }
    printf("No");
    return 0;
  }
  if(i>7 && i<12){
    for(int j=8;j<12;j++){
      if(group[j]==y){
	printf("Yes");
	return 0;
      }
    }
    printf("No");
    return 0;
  }
  if(i>12 && y==2){
    printf("Yes");
    return 0;
  }else{
    printf("No");
    return 0;
  }
