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(){
int a,b;
scanf("%d%d",&a,&b);
if(a==2){
a=3;
}else if(a==4 || a==6 || a==9 || a==11){
a=2;
}else{
a=1;
}
if(b==2){
b=3;
}else if(b==4 || b==6 || b==9 || b==11){
b=2;
}else{
b=1;
}
printf(a==b?"Yes":"No");
return 0;}
