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;
  vector<int>V;
  for(int i=1;i<=9;i++){
    if(n%i==0) V.push_back(n/i);
  }
  int l=V.size();
  int ct=0;
  for(int i=0;i<l;i++){
    //cout<<V[i]<<endl;
    if(V[i]<=9 && V[i]>=1) ct++;
  }
  if(ct>=1) cout<<"Yes"<<endl;
  else cout<<"No"<<endl;
}
