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 Java7 (OpenJDK 1.7.0) (judge verdict: Accepted)

import java.util.*;

class Main {
  public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    int a = sc.nextInt();
    boolean result = false;
    for(int i = 1; i < 10; i++) {
	    for(int j = 1; j < 10; j++) {
          int x = i * j;
          if(a == x) {
            result = true;
            break;
          }
        }
      if(result) {
        break;
      }
    }
    
    if(result) {
      System.out.println("Yes");
    } else {
      System.out.println("No");
    } 
  }
}
