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 Python (3.8.2) (judge verdict: Wrong Answer)

num = int(input())
c = False
for i in range(1,10):
    if num % i : continue
    n1 = num/i
    n2 = num/n1
    if ((n1 * n2) == num) and (n1 < 10 and n2 < 10): 
        c = True
        break

if c:
    print('yes')
else:
    print('no')
