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

# include <stdio.h>

int main(){
    int g1[7] = {1, 3, 5, 7, 8, 10, 12};
    int g2[4] = {4, 6, 9, 11};
    int g3 = 2;
    int x, y;
    int a= 0, b = 0, c =0;
    scanf("%d %d", &x, &y);
    
    for (int i = 0; i < 7; ++i){
        if (x == g1[i])
            a = 1;
        if (y == g1[i])
            b = 1;
    }
    if (a == 1 && b == 1){
        printf("Yes\n");
        c = 1;
    }
    
    a = 0, b = 0;
        
    for(int i =0; i < 5; ++i){
        if (x == g2[i])
            a = 1;
        if (y == g2[i])
            b = 1;
    }
    if (a == 1 && b == 1){
        printf("Yes\n");
        c = 1;
    }
    if (x == 2 && y == 2)
        printf("Yes\n");

    if (c == 0)
