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 group[2];
	for (int i = 0; i < 2; i++) {
		int n;
		scanf("%d", &n);
		switch (n)
		{
		case 4:
		case 6:
		case 9:
		case 11:
			group[i] = 1;
			break;
		case 2:
			group[i] = 2;
			break;
		default:
			group[i] = 0;
			break;
		}
	}

	if (group[0] == group[1])	printf("Yes");
	else	printf("No");

	return 0;
}
