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) {
      
        // flag
        boolean flag = false;

		// argumentの取得
		Scanner sc = new Scanner(System.in);

		int x = sc.nextInt();
	    //int y = sc.nextInt();
      
        // 総当たり
        for (int i=1; i < 10; i ++) {
          for (int j = 1; j < 10; j++) {
            if ( x == (i * j)) {
              System.out.println("Yes");
              flag = true;
            } else {
              // do nothing
            }
          }
        }
      
        if (flag == false) {
          System.out.println("No");
        }
	}
