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

#include <stdio.h>
void main()
{
  int n , a , i , j , f=0;
  scanf("%d",&n);
  for(i=10;i>0;i++)
  {
    if(n%i==0)
    {
      a = n/i;
      for (j=10;j>0;j++)
      {
        if(a%j==0)
        {
          f = 1;
          printf("yes");
          break;
        }
        
      }
      if(f==1)
        break;
    }
  }
  if(f==0)
    printf("no");
}
