Problem Statement

Having learned the multiplication table, Takahashi can multiply two integers between 1 and 9 (inclusive) together.

Given an integer N, determine whether N can be represented as the product of two integers between 1 and 9. If it can, print Yes; if it cannot, print No.

Constraints

1 \leq N \leq 100

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N can be represented as the product of two integers between 1 and 9 (inclusive), print Yes; if it cannot, print No.

Sample Input 1

10

Sample Output 1

Yes

10 can be represented as, for example, 2 \times 5.

Sample Input 2

50

Sample Output 2

No

50 cannot be represented as the product of two integers between 1 and 9.

Sample Input 3

81

Sample Output 3

Yes

Solution in Haskell (GHC 7.10.3) (judge verdict: Accepted)

module Main where

import           Data.Maybe                     ( fromJust )
import           Data.List
import           Control.Monad
import qualified Data.ByteString.Char8         as BS

bytestr2Int = fst . fromJust . BS.readInt
getInt = bytestr2Int <$> BS.getLine

main :: IO ()
main = do
    n <- getInt
    putStrLn $ check n

check n = if 82 < n
    then "No"
    else if or [ m * l == n | m <- [1 .. 9], let l = div n m, l < 10 ]
        then "Yes"
        else "No"
