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 Java8 (OpenJDK 1.8.0) (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        // 整数の入力
        int N = Integer.parseInt(sc.next());
        String ans = "NO";
        int[] a = {1, 2, 3, 4, 5, 6, 7, 8, 9};
        int[] b = {1, 2, 3, 4, 5, 6, 7, 8, 9};

        if (N > 81) {
            ans = "NO";
        } else {
            for (int i = 0; i < 9; i++) {
                for (int j = 0; j < 9; j++) {
                    if (N == (a[i] * b[j])) {
                        ans = "YES";
                    }
                }
            }
        }
        // 出力
        System.out.println(ans);

    }
