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 x, y;
	
	scanf("%d %d", &x, &y);
	
	if(x == 2 && y == 2)
		printf("Yes\n");
	else if( (x != 2 && y!= 2) 
		&& ( ( (x<8) && (x%2 == 1) ) || ( (x>7) && (x%2 == 0) ) )
		&& ( ( (y<8) && (y%2 == 1) ) || ( (y>7) && (y%2 == 0) ) ) )
		printf("Yes\n");
	else if( (x != 2 && y!= 2)
		&& ( ( (x<8) && (x%2 == 0) ) || ( (x>7) && (x%2 == 0) ) )
		&& ( ( (y<8) && (y%2 == 0) ) || ( (y>7) && (y%2 == 0) ) ) )
		printf("Yes\n");
	else
		printf("No");
	
	return 0;
