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 = 0, y = 0;
	scanf("%d %d", &x, &y);

	int group[12] = {1, 3, 1, 2, 1, 2, 1, 1, 2, 1, 2, 1};

	if(group[x-1] == group[y-1]) printf("Yes\n");
	else printf("No\n");

	return 0;
}
