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 OCaml (4.02.3) (judge verdict: Accepted)

open List;;
Scanf.scanf "%d %d" @@ fun x y -> print_endline @@
  if x = 2 || y = 2 then "No"
  else if exists (fun g -> mem x g && mem y g) [[1; 3; 5; 7; 8; 10; 12]; [4; 6; 9; 11]] then "Yes"
  else "No"
