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 C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

using System.Collections.Generic;

class Program {
    static void Main(string[] args) {

        int N = int.Parse(Console.ReadLine());


        string result = "No";

        for(int a = 1; a <= 9; a++) {
            for(int b = 1; b <= 9; b++) {
                if (N == a * b) {
                    result = "Yes";
                }
            }
        }

        Console.WriteLine(result);
    }
}
