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

#include <stdio.h>

int main(void) {
    int num;

    //入力を受け取る
    scanf("%d", &num);

    int i = 1;

    //numが各数字で割り切れ、かつその商が１から９の間であるとき、Yesを表示
    for(i; i < 10; i++){
        if(num % i == 0 && num / i <= 9){
            printf("Yes\n");
            break;
        }
    }

    if(i == 10){
        printf("No\n");
         //どれにも当てはまらなかった場合はNoを表示
    }
    
    return 0;
}
