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)

#!/usr/bin/perl

use strict;
use warnings;

my $n = <STDIN>;
my $c = 0;
for (my $i=1; $i<10; $i++)
{
    for (my $j=1; $j<10; $j++)
    {
        if ($n==$i*$j) {
            $c = 1;
            last;
        }
    }
    if ($c) {
        last;
    }
}

print "Yes\n" if $c==1;
print "No\n" unless $c==1;
