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`.

Examples

Input

1 3


Output

Yes


Input

2 4


Output

No
import sys
input = map(int, raw_input().split())
group1 = [1,3,5,7,8,10,12]
group2 = [4,6,9,11]
group3 =  [2]

syozoku = [0,0]

for i in range(2):
	if input[i] in group1:
		syozoku[i] = 1
	elif input[i] in group2:
		syozoku[i] = 2
	elif input[i] in group3:
		syozoku[i] = 3

#print(syozoku[0])
#print(syozoku[1])
if syozoku[0] == syozoku[1]:
	print("Yes")
else:
	print("No")
