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 C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Collections.Generic;

namespace ABC144_B
{
    class Program
    {
        static void Main(string[] args) {
            int n = int.Parse(Console.ReadLine());

            string strAns = "No";
            int intAns = 0;

            var list = new List<int>();
            var arr = new int[n];

            for(int i = 1; i < 10; i++) {
                if(n % i == 0) {
                    if ((n / i) <= 9) {
                        strAns = "Yes";
                    }
                }
            }


            Console.WriteLine(strAns);
        }
    }
}
