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>

#include <math.h>


int main(void)
{	
	int x,y;
	scanf("%d %d",&x,&y);
	
	if(x==2){
		x='c';
	} else if(x==4 || x==6 || x==9 || x==11){
		x='b';
	} else{
		x='a';
	}
	
	if(y==2){
		y='c';
	} else if(y==4 || y==6 || y==9 || y==11){
		y='b';
	} else{
		y='a';
	}
	
	if(x==y){
		puts("Yes");
	} else{
		puts("No");
	}
	
	return 0;
