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 PRM = {
		answer : 'No'
	}

	var init = function(){
		if( EXE.checkNum( number ) ) EXE.execute( number );
		console.log( PRM.answer );
	}
	
	var EXE = {
		checkNumber : function( n ){
			if( !Number.isInteger( n ) || ( n < 1 || 100 < n ) )
				console.log( 'error' ); // 要仕様確認
			else
				return true;
		},
		execute : function( n ){
			var resMath = ( index )=> {
				var r = n / index;
				if( Number.isInteger( r ) && r < 10 ) return true;
				else return false;
			}
	
			var i = 1, l = 10;
			for( ; i < l; i = ( i + 1 )|0 ){
				if( resMath( i ) ){
					PRM.answer = 'Yes';
					break;
				}
			}
		}
	}
	return init;
	
}
