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: Wrong Answer)

#include <stdio.h>

int main(void){
	int a[7] = {1, 3, 5, 7, 8, 10, 12};
	int b[4] = {4, 6, 9, 11};
	int c[1] = {2};
	
	int x, y, groupx, groupy;
	scanf("%d%d", &x, &y);
	
	for(int i=0; i<=6; i++){
		if(x == a[i])groupx = 0;
		if(y == a[i])groupy = 0;
	}
	for(int i=0; i<=3; i++){
		if(x == b[i])groupx = 1;
		if(y == b[i])groupy = 1;
	}
	if(x == c[0])groupx = 2;
	if(y == c[0])groupy = 2;
	
	if(groupx == groupy){
		printf("yes\n");
	}else{
		printf("no\n");
	}
}
