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>
#define rep(i,n) for(int i=0; i<(n); i++)

using namespace std;

typedef long long ll;
typedef pair<int, int> P;
const int INF = 1000000;

signed main()
{
    int n; cin >> n;
    int dp[101];
    rep(i,9) rep(j,9) {
        dp[(i+1) * (j+1)] = 1;
    }
    
    string ans;
    if (dp[n] == 1) {
        ans = "Yes";
    } else {
        ans = "No";
    }
    cout << ans << endl;
