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 Common Lisp (SBCL 1.1.14) (judge verdict: Accepted)

(defun solve (N)
  (let (x y)
    (do ((i (isqrt N) (1- i)))
	((zerop i) "No")
      (multiple-value-bind (x y) (floor N i)
	  (if (and (= y 0) (< x 10))
	      (return "Yes") )))))

(princ (solve (read)))
