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 num;
    int condition = 0; // is num a product of integers between 1 and 9
    scanf("%d", &num);
    
    if(1 <= num && num <= 81){  // num should be between 1(1*1) and 81(9*9) 
        for (int i = 1; i <= 9; i++){
            int quotient = num / i;
            int remainder = num % i;
            if((1 <= quotient && quotient <= 9) && (remainder == 0))
                condition = 1;
        }
    }

    if(condition) 
        printf("Yes");
    else 
        printf("No");

    return 0;
}
