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: Runtime Error)

using System;

public class Test
{
	public static void Main()
	{
		// your code goes here
		int n = int.Parse(Console.ReadLine());
		int a = n/10;
		if(n%10==0){a++;}
		int counter = 0;
		
		for(int i=a;i!=10;i++){
			if(n%i==0){counter++;}
		}
		
		if(counter==0){
			Console.WriteLine("No");
		}else{
			Console.WriteLine("Yes");
		}
		
	}
