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

import java.util.*;
public class Main{
	public static void main(String[] args) {
		Scanner t=new Scanner(System.in);
		int x;
		x=t.nextInt();
		boolean ok=false;
		for(int i=0;i<=9;i++) {
			for(int j=0;j<=9;j++) {
				if(i*j==x) {ok=true; break;}
			}
		}
		if(ok==true) {
			System.out.println("Yes");
		}
		else {
			System.out.println("No");
		}
		t.close();
