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: Accepted)


#include "stdio.h"
#include "stdbool.h"

int hoge(int N){
    for(int i=1;i<=9;i++){
        if(N%i==0){
            int x=N/i;
            if(1<=x & x<=9){
                return 1;
            }
        }
    }
    return 0;
}

int main(){
    int N;
    scanf("%d",&N);

    if(hoge(N)){
        printf("Yes");
    } else{printf("No");}



    return 0;
}
