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)

a = gets.to_i
num = [9,8,7,6,5,4,3,2]
re = 0
num.each do |n|
    if a%n==0
        a = a / n
        re = n
        puts "#{a}, #{re}"
        break
    end
end

if re < 10 && a < 10
    puts "Yes"
else
    puts "No"
end
