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>

int main() {
    int x,y;
    int z = 0;
    scanf("%d",&x);
    for (int i = 1; i < 10; i++) {
        for (int j = 1; j < 10; j++) {
            y = i*j;
            if (y==x) {
                printf("Yes");
                z = 1;
                break;
            }
        }
        if (z==1) {
            break;
        }
        
    }
    if (z == 0) {
        printf("No");
    }
}
