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

int main(void){

        int N=0;
        int flag = 0;
        scanf("%d",&N);

        for(int i=2;i<10;i++){
                if(N%i == 0){ 
                        if(N/i < 10){
                                printf("Yes\n");
                                i = 20; 
                                flag = 1;
                        }   
                }   
        }   
        if(!flag){
                printf("No\n");
        }   

        return 0;
