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)

#include <stdio.h>

int main(){
    int n;
    scanf("%d", &n);
    int c = 0;
    int a, b;
    for (int i = 1; i <= 9; i++){
        a = n % i;
        b = n / i;
        if (a == 0 && b >= 1 && b <= 9){
            c = 1;
          	break;
        }
    }
    if (c == 1){
        printf("Yes");
    } else {
      printf("NO");
    }
    return 0;
}
