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 JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

function Main(input) {
   
    var N = input[0].trim();

//	console.log("%s",N);

  	var result = N;
  	var sosu = 9;
  
    do{
      
      while(result % sosu == 0){
         result = result / sosu;
//        console.log("sosu:%s",sosu);

      }
      sosu--;

    }while(result != 1 && sosu> 0)

    console.log("%s",result == 1 ? "YES":"NO");

}

Main(require("fs").readFileSync("/dev/stdin", "utf8").split("\n"));
