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 na[7]={1,3,5,7,8,10,12},nb[4]={4,6,9,11},i,j,a,b,flag;
	a=b=flag=0;
	scanf("%d %d",&a,&b);
	for(i=0;i<7;i++){
		if(na[i]==a){
			for(j=0;j<7;j++){
				if(na[j]==b){
					flag=1;
					break;
				}
			}
	//	break;
		}
	}
	if(flag==0){

			//break;
			}
		}
	}
	
	if(flag==1){
		printf("Yes");
	}
	else{
