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 <stdlib.h>

int main(int argc, char *argv[]) {
	int x, y;
	scanf("%d%d", &x, &y);
	if(x == 2 && y != 2){
		printf("No\n");
		return 0;
	}
	else{
		if((x==1 || x == 3 || x==5|| x == 7 || x == 8 || x == 10 || x == 12) && (y==1 || y == 3 || y==5||y == 7 || y == 8 || y == 10 || y == 12)){
			printf("Yes\n");
		}
		else if((x == 4 || x == 6|| x == 9 || x == 11) && (y == 4 || y == 6|| y == 9 || y == 11)){
			printf("Yes\n");
		}
		else{
			printf("No\n");
		}
	}

	return 0;
