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 (Clang 3.8.0) (judge verdict: Accepted)

#include<stdio.h>
int main()
{
	int A, B;
	int a, b, c, i;
	scanf("%d", &a);
	for (i = 1; i <= 9; i++)
		for (b = 1; b <= 9; b++)
			if (a == i * b)
			{printf("Yes\n"); return 0;
              }
				printf("No");
  return 0;
}
