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 PHP7 (7.0.15) (judge verdict: Accepted)

<?php

   $N = fgets(STDIN);

    $KU = [1, 2, 3, 4, 5, 6, 7, 8, 9];

     $KU2 = [1, 2, 3, 4, 5, 6, 7, 8, 9];

    $jud = "No";

   for ($i = 0; $i < 9; $i++) {

             for ($j = 0; $j < 9; $j++) {

                       $res = $KU[$i] * $KU2[$j];

                              if ($N == $res) {
                                   $jud = "Yes";
                                  break;
                        }
               }
              

      }

echo $jud;
