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

<?php
$n = trim(fgets(STDIN));
  $or = true;
  for($i=1;$i<=sqrt($n);$i++) {
    if($n%$i==0) {
      if($i<10 && $n/$i<10) {
        echo "Yes";
        $or = false;
        break;
      }
    }
  }
  if($or) {
    echo "No";
  }
