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: Runtime Error)

a, b = gets.split.map(&:to_i)
unless a < 10 && b < 10
  puts -1 
else
  puts a*b
end

n=gets.to_i
(1..9).each do |x|
(1..9).each do |y|
  if x * y == n
    puts 'Yes'
    exit(0)
  end
end
end
puts 'No'
