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(){
    int a,b,i;
    scanf("%d",&a);
    for(i = 9; i > 4; i--){
        b = a/i;
        if(a%i == 0 && b <= i){
            printf("Yes\n");
            break;
        } 
        else if(i == 5 && a % i != 0){
            printf("No\n");
            break;
        }
        else if(i == 5 && b > i){
            printf("No\n");
            break;
        }
    }
        
    return 0;
}
