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 Perl (v5.18.2) (judge verdict: Accepted)

my $N = <STDIN>;
chomp($N);
foreach my $i (1..9) {
    my $m = $N % $i;
    if ($m == 0) {
        my $a = $N/$i;
        if ( $a < 10 and $a > 0 ) {
            print "Yes";
            exit 0;
        }
    }
}
print "No";
