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

#include<bits/stdc++.h>
using namespace std;
#define REP(i, n) for(int i=0, i##_len=(n); i<i##_len; ++i)
typedef long long ll;
#define pb push_back
void Yes() {cout << "Yes" << endl;}
void No() {cout << "No" << endl;}
void YES() {cout << "YES" << endl;}
void NO() {cout << "NO" << endl;}

void solve(){
    int n; cin >> n;
    for(int i=1; i<=9;i++){
        for(int j=1; j<=9; j++){
            if(i*j == n){
                Yes();
                exit(0);
            }
        }
    }
    No();
}

int main(){
    cin.tie(0);
    ios::sync_with_stdio(false);
    solve();
