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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <iostream>
int main(){
int x,y;
std::cin >> x >> y;
if(x==2 || y==2)
std::cout << "No" << std::endl;
else if(y==6 || y==9 || y==11 &&x==4)
std::cout << "Yes" << std::endl;
else if(y==9 || y==11 && x==6)
std::cout << "Yes" << std::endl;
else if(x==9 && y==11)
std::cout << "Yes" << std::endl;
else if(y==3 || y==5 || y==7 || y==8 || y==10 || y==12 &&x==1)
std::cout << "Yes" << std::endl;
else if(y==5 || y==7 || y==8 || y==10 || y==12 &&x==3)
std::cout << "Yes" << std::endl;
else if(y==7 || y==8 || y==10 || y==12 &&x==5)
std::cout << "Yes" << std::endl;
else if(y==8 || y==10 || y==12 && x==7)
std::cout << "Yes" << std::endl;
else if(y==10 || y==12 &&x==8)
std::cout << "Yes" << std::endl;
else if(x==10 && y==12)
std::cout << "Yes" << std::endl;
else
std::cout << "No" << std::endl;
