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 C (GCC 5.4.1) (judge verdict: Wrong Answer)

/* ex_3-4. nknm */

#include <stdio.h>

int main(void){

    //Nを入力
    int N;
    int i;
    

    scanf("%d", &N);

    //Nがiで割り切れ商が９以下の時のみyesを表示
    for(i = 1; i <= 9; i++){
        if(N / i <=9 && N % i == 0){
            printf("yes\n");
            break;
        }else if(i == 9 && N % i != 0){
            printf("no\n");
        }
    }
    return 0;
}
