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)

x, y = map(int, input().split())
a = [1,3,5,7,8,10,12]
b = [4,6,9,11]
c = [2]
if x in c or y in c:
	print ("No")
	exit()
if (x in a and y in a) or (x in b and y in b):
	print ("Yes")
else:
	print ("No")
