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 Ruby (2.3.3) (judge verdict: Wrong Answer)

N = gets.to_i
num1 = 1
num2 = 1
ans = false

8.times do
    num1 += 1
    num2 = 1
    8.times do
        num2 += 1
        if N == num1 * num2
            ans = true
        end
    end
end

if ans
    puts "Yes"
else
    puts "No"
end
