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