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 Python (3.4.3) (judge verdict: Accepted)

import sys

x,y = map(int, sys.stdin.readline().split())

group = [0] * 13
group[2] = 2
for i in [4,6,9,11]:
    group[i] = 1

if group[x] == group[y]:
    print("Yes")
else:
    print("No")
