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 Pascal (FPC 2.6.2) (judge verdict: Wrong Answer)

var
        n,i,j:byte;
        ok:boolean;
begin
        read(n);
        ok:=false;
        for i:=2 to 9 do
                for j:=2 to 9 do if i*j=n then ok:=true;
        if ok=true then write('Yes') else write('No');
end.
