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(void){
	int x,y;
	int i,j;
	scanf("%d",&x);
	scanf("%d",&y);
	if(1<=x&&x<y&&y<=12){
		if(x==1||x==3||x==5||x==7||x==8||x==10){
			if(y==3||y==5||y==7||y==8||y==10||y==12){
			printf("Yes");
			}else{
				printf("No");
			}
		}else if(x==4||x==6||x==9){
			if(y==6||y==9||y==11){
				printf("Yes");
			}else{
			printf("No");
			}
		}else if(x==2||x==11){
			printf("No");
		}
	}
	
	return 0;
