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 (3.4.3) (judge verdict: Wrong Answer)

n = int(input())
if n % 9 == 0:
    a = n/9
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 8 == 0:
    a = n/8
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n %7 == 0:
    a = n/7
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 6 == 0:
    a = n/6
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 5 == 0:
    a = n/5
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 4 == 0:
    a = n/4
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 3 == 0:
    a = n/3
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n % 2 == 0:
    a = n/2
    if a < 10:
        print("Yes")
    else:
        print("No")
elif n == 1:
    print("Yes")
