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: Accepted)

'use strict';

function main(input) {
  const arr = input.trim().split('\n');
  const a = Number(arr[0]);
  let b = 0;
  let isKuku = false;

  for (let i = 1; i <= 9; i++) {
    if (a % i === 0) {
      b = a / i;
      if (b >= 1 && b <= 9) {
        isKuku = true;
      }
    }
  }

  console.log(isKuku ? 'Yes' : 'No');
}

main(require("fs").readFileSync("/dev/stdin", "utf8"));
