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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <bits/stdc++.h>
using namespace std;
 
int main(){
    int N;
    cin >> N;
    int sensor=0;
    for(int i = 1; i < 10; i++){
        for(int j = 1; j < 10; j ++){
            if( N == i * j){
                cout << "Yes" << endl;
                sensor = 1;
                break;
            }
        }
    if(sensor == 1){
        break;
    }
    }
    if(sensor == 0){
        cout << "No" << endl;
    }

}
