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)

a,b=gets.split.map(&:to_i)
if a==2 then a=2
elsif (a<=7&&a%2==1)||(a>=8&&a%2==0) then a=0
else a=1 end
if b==2 then b=2
elsif (b<=7&&b%2==1)||(b>=8&&b%2==0) then b=0
else b=1 end
puts a==b ? "YES":"NO"
