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>81:
    print("No")
    exit()
elif n<10:
    print("Yes")
    exit()
elif n%2==0:
    a = n/2
    if a<10:
        print("Yes")
        exit()
elif n%3==0:
    a = n/3
    if a<10:
        print("Yes")
        exit()
elif n%4==0:
    a = n/4
    if a<10:
        print("Yes")
        exit()
elif n%5==0:
    a = n/5
    if a<10:
        print("Yes")
        exit()
elif n%7==0:
    a = n/7
    if a<10:
        print("Yes")
        exit()
elif n%8==0:
    a = n/8
    if a<10:
        print("Yes")
        exit()
elif n%9==0:
    a = n/9
    if a<10:
        print("Yes")
        exit()
print("No")
