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

/*3.4 hightierra*/
#include <stdio.h>
 
int main(void){
    //変数Nを定義、値を入力
    int N;
    scanf("%d",&N);
 
    int i,j; //掛け算する数
    int judge = 0; //九九で表せるかの判定
 
    /*二重ループで九九にあるかを判定*/
    for(i=1; i<10; i++){
      	for(j=1; j<10; j++){
          if(N == i*j){
            judge = 1; //表せたらjudgeを１に
            break; //内側for文を抜ける
          }
      	}
        if(judge){
            break; //外側for文を抜ける
        }
    }
    // 判定
    if(judge){
      	printf("Yes\n");
    }else{
      	printf("No\n");
    }
 
    return 0;
