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 Java8 (OpenJDK 1.8.0) (judge verdict: Wrong Answer)

import java.util.*;

public class Main
{
	public static void main(String[] args)
	{
		Scanner scan = new Scanner(System.in);
		int N = scan.nextInt();
		boolean flag = false;


		if(N >=1 && N<=81)
		{
			for(int i = 1; i<=9; i++)
			{
				if( ((N%i) == 0) && ((N/i) <= 9) )
					flag = true;
			}
		}
		else
			System.out.println("No");

		if(flag == true)
			System.out.println("Yes");
	}
