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.Scanner;

public class Main {
	public static void main(String args[]) {
		
		Scanner scanner = new Scanner(System.in);

		int num = scanner.nextInt();
		scanner.close();
		
		
		int a[] = {1,2,3,4,5,6,7,8,9,10,12,14,15,16,18,20,21,24,25,27,28,30,
				32,35,36,40,42,45,48,54,56,63,64,72,81};
		boolean flg = false;
		for(int i = 0; i < a.length; i++) {
			if(a[i] == num) {
				System.out.println("YES");
				flg = true;
				break;
			}
		}
		
		if(!flg) {
			System.out.println("NO");
		}
	}
