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 {
	public static void main(String[] args) {
 		Scanner scanner = new Scanner(System.in);
 		int N = scanner.nextInt();
 		int count = 0;
 		if (N == 1) {
 			count += 1;
 		}
 		for (int i = 2; i <= 9; i++) {
 			int x = N % i;
 			if (x == 0) {
 				int y = N / i;
 				if (y <= 9) {
 					count += 1;
 					//System.out.println(i);
 					break;
 				}
 			}
 		}
 		if (count > 0) {
 			System.out.println("Yes");
 		} else {
 			System.out.println("No");
 		}
	}
}
