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: Wrong Answer)

import sys
a=list(map(int,input().split()))
flg=0
A=[1,3,5,7,8,10,12]
B=[4,6,9,11]
C=[2]
for i in range(len(A)):
    if A[i]==a[0]:
        for j in range(len(A)):
            if A[j]==a[1]:
                flg=1
for i in range(len(B)):
    if B[i]==a[0]:
        for j in range(len(B)):
            if B[j]==a[1]:
                flg=1
if flg==1:
    print("YES")
else:
    print("NO")
