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: Runtime Error)

import sys

X, Y=map(int,input().split())

if X==2 or Y==2:
  print('No')
  sys.exit()
elif X==4 or X==6 or X==9 or X==11:
  if Y==6 or Y==9 or Y==11:
    print('Yes')
    sys.exit()
  else:
    print('No')
    sys.exit()
else:
  if Y==3 or Y==5 or Y==7 or Y==8 or Y==10 Y==12:
    print('Yes')
    sys.exit()
  else:
    print('No')
    sys.exit()
