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 n, i, for_flag = 1;           // 変数宣言
    scanf("%d", &n);                  // n, kを入力

    for(i = 9; 0 < i; i--){           // 1から9で除算
        if(n / i < 10 && n % i == 0){ // 商が10未満かつ余りが0の場合
            printf("Yes\n"); for_flag--; break;   // "Yes"を出力し、ループを終了する
        }
    }
    if(for_flag){
        printf("No\n");
    }
    return 0;
}
