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: Wrong Answer)

#include<stdio.h>
int main(void){
    int a,b,c,d=0,i,e=0;
    scanf("%d",&a);
    for(i=1;i<=9;i++){
        b=1;
        c=a%b;
        e=a/b;
        b++;
        if(c==0&&e<=9&&e>=1){
            d++;
        }
    }
    if(d>=1){
        printf(" Yes");
    }else if(d==0){
        printf(" No");
    }
    return 0;
}
