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 = (int(i) for i in input().split())

if x == 2 or y == 2:
  print('No')
  exit()
if x == 4 or  x == 6 or x == 9 or x == 11:
  if y == 4 or y == 6 or y == 9 or y == 11:
    print('Yes')
  else:
    print('No')
else:
  if y == 4 or y == 6 or y == 9 or y == 11:
    print('No')
  else:
    print('Yes')
