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 n,i,j,m,y=0;
    scanf("%d",&n);
    for(i=1; i<10; i++)
    {
        for(j=1; j<10; j++)
        {
            m=i*j;
            if(n==m)
            {
                printf("Yes\n");
                y++;
                break;
            }
            if(y==1)
            {
                break;
            }

        }
    }
    if(y==0)
            {
                printf("No\n");
            }
}
