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())
ans = []
for i in [x, y]:
    if i in [1, 3, 5, 7, 8, 10, 12]:
        ans.append(1)
    elif i in [4, 6, 9, 11]:
        ans.append(2)
    else:
        ans.append(3)
if ans[0] == ans[1]:
    print("Yes")
else:
    print("No")
