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){
    //Nをnumberとする。
    int number;
    int factor=0;

    // number の入力を取得
    scanf("%d",&number);

    // factorを総当たり
    // 割り切れるものがあればyes、なければNoを出力
    for(factor=1;factor<10;factor++){
        //numberがiで割り切れてかつ商が9以下ならいい。
        if(number % factor == 0 && number/factor < 10){
            printf("Yes");
            return 0;
        } 
    }
    printf("No");
    return 0;
}
