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

class Program
{
    static void Main()
    {
        int N = int.Parse(Console.ReadLine());
        bool flg = false;
        for (int i = 1; i < 10; i++)
        {
            for (int j = 1; j < 10; j++)
            {
                if (i * j == N)
                {
                    flg = true;
                    break;
                }
            }
            if (flg) break;
        }
        Console.WriteLine(flg ? "Yes" : "No");
        return;
    }
}
