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 Ruby (2.3.3) (judge verdict: Accepted)

x, y = gets.split.map(&:to_i)

def group(x)
  case x
  when 2
    1
  when 4, 6, 9, 11
    2
  else
    3
  end
end

puts group(x) == group(y) ? 'Yes' : 'No'
