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: Accepted)

n = int(input())

flag = 0

for i in range(9):
  i += 1
  if (n > 81):
    flag = 1
    break
  if n % i == 0:
    if (0 <= n/i <= 9):
      break
    else:
      continue
  else:
    if (i == 9):
      flag = 1
    else:
      continue

if (flag == 0):
  print("Yes")
else:
  print("No")
