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

        Scanner sc = new Scanner(System.in);
        BigInteger N = new BigInteger(sc.next());

        boolean b = false;
        for (int i=1; i<10; i++) {
            for (int j=i+1; j<10; j++) {
                if (N.intValue()==i*j) {
                    b = true;
                    break;
                }
            }

        if (b)
            System.out.println("Yes");
        else
            System.out.println("No");
    }
