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 (2.7.1) (judge verdict: Accepted)

def divisor(num)
    num_sqrt = Math.sqrt(num).floor
    (1..num_sqrt).select{ |i| num % i == 0 }
end

n = gets.to_i

divisions = divisor(n)

divisions_list = []

divisions.each do |d|
    b = n/d
    arr = [d, b]
    divisions_list.push(arr)  
end

divisions_list.each do |d|
    d_len = d[0].to_s.length 
    b_len = d[1].to_s.length
    if d_len == 1 && b_len == 1
        puts("Yes")
        exit
    end
end

puts("No")
