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: Accepted)


import java.util.Scanner;

public class Main {

	public static void main(String[] args) {

		/*
		 * Scannerで値取得。
		 */
		Scanner sint = new Scanner(System.in);

		//値取得
		int numN = sint.nextInt();

		sint.close();
		
		//計算可能な値上限
		final int KEISANKANOU = 10;

		int waru = 0;
		int sho = 0;
//		割り切れるか判定→割れれば割ってみる
		for(waru = 1; waru < KEISANKANOU; waru++) {
			if(numN % waru == 0) {
				sho = numN / waru;
			}
		}
		//shoが１０未満か判定
		if(sho < KEISANKANOU) {
			System.out.println("Yes");
		}else {
			System.out.println("No");
		}
	}
