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: Wrong Answer)

x,y=gets.split.map(&:to_i)
a=[1,3,5,7,8,10,12]
b=[4,6,9,11]
c=[2]

r=->ar{ar.index(x)&&ar.index(y)}

if r[a]||r[b]||r[c] then
    puts "yes"
else
    puts "no"
end
