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: Accepted)

import java.util.Scanner;

public class Main {
	Scanner sc = new Scanner(System.in);
	
	void a() {
		int a = sc.nextInt(), b = sc.nextInt();
		String aStr = Integer.toString(a),bStr = Integer.toString(b);
		if(aStr.length() >= 2 || bStr.length() >= 2) {
			System.out.println("-1");
			return;
		}else {
			System.out.println(a*b);
		}
	}
	
	
	void b() {
		int n = sc.nextInt();
		for(int i = 1;i <= 9;i ++) {
			if(n % i == 0) {
				String s = Integer.toString(n/i);
				if(s.length() == 1) {
					System.out.println("Yes");
					return;
				}
			}
		}
		System.out.println("No");
	}
	
	public static void main(String[] args) {
		new Main().b();
	}
}
