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.*;
class Main{
  public static void main(String[] args){
    Scanner scan=new Scanner(System.in);
    int N=scan.nextInt();
    int l=1;
    int h=N;
    int l_tmp=1;
    int h_tmp=N;
    while(h-l>1){
      if(l*h<N){
        while(l*h<N){
          l++;
        }
      }
      if(l*h>N){
        while(l*h>N){
          h--;
        }
      }
      if(l*h==N){
        l_tmp=l;
        h_tmp=h;
        l++;
        h--;
      }
    }
  
    if(l_tmp<=9&&h_tmp<=9){
      System.out.println("Yes");
    }else{
      System.out.println("No");
    }
  }
