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)

let a = [1;3;5;7;8;10;12];;
let b = [4;6;9;11];;
let c = [2];;

let (x, y) = Scanf.scanf "%d %d" (fun x y -> (x, y));;
let ans =
  if List.mem x a && List.mem y a then
    "Yes"
  else if List.mem x b && List.mem y b then
    "Yes"
  else if List.mem x c && List.mem y c then
    "Yes"
  else
    "No";;
let () = print_endline ans;;
