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: Accepted)

=begin
1, 1 ~ 9 の配列を作ってそれぞれ判定する(to_a = i)
2, n / i < 10 かつ n % i　== 0　に数値を any? で判定する
  2.1, any? は 全ての要素が 真 の時に true を返し、それ以外は false を返す
3, 三項演算子で 結果を 出力する
=end

n = gets.to_i

puts (1..9).to_a.any?{|i| n / i < 10 && n % i == 0} ? "Yes" : "No"
