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 Fortran (gfortran v4.8.4) (judge verdict: Wrong Answer)

program abc144b
   implicit none
   integer :: N, i

   read(*,*) N

   do i = 1, 9
      if (mod(N,i) == 0) then
         if (N/i <= 9) then
            write(*,*) "YES"
            stop
         end if
      end if
   end do

   write(*,*) "NO"

end program abc144b
