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 a;
	scanf("%d",&a);
	if(a<=10||a==12||a==14||a==16||a==18||a==15||a==21||a==24||a==27||a==20||a==28||a==32||a==36||a==25||a==30||a==35||a==40||a==45||a==42||a==48||a==54||a==49||a==56||a==63||a==64||a==72||a==81)
	printf("Yes");
	else printf("No");
	return 0;
}
