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){
    //標準入力
    int num;
    scanf("%d",&num);
    for(int i=1;i<10;i++){
        //nがiで割り切れてなおかつその商が10未満なら
        if(num%i == 0 && num/i < 10){
            printf("Yes\n");
            break;
        }
        //最後までbreakされなかったら九九にはない
        if(i == 9)
            printf("No\n");
    }

    return 0;
