Problem Statement

1 yen (the currency of Japan)

6 yen, 6^2(=36) yen, 6^3(=216) yen, ...

9 yen, 9^2(=81) yen, 9^3(=729) yen, ...

At least how many operations are required to withdraw exactly N yen in total?

It is not allowed to re-deposit the money you withdrew.

Constraints

1 \leq N \leq 100000

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If at least x operations are required to withdraw exactly N yen in total, print x.

Sample Input 1

127

Sample Output 1

4

By withdrawing 1 yen, 9 yen, 36(=6^2) yen and 81(=9^2) yen, we can withdraw 127 yen in four operations.

Sample Input 2

3

Sample Output 2

3

By withdrawing 1 yen three times, we can withdraw 3 yen in three operations.

Sample Input 3

44852

Sample Output 3

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

function Main(str) {
    str=str.split(/\n/);
    var one = [1];
    var sixbox=[];
    var nightbox=[];
    for(var i = 0; i<10; i++){
        sixbox[i]=(Math.pow(6,i));
        nightbox[i]=(Math.pow(9,i+1));
    }
    var total = sixbox.concat(nightbox);
    function compareFunc(a, b) {
        return (a < b ? 1 : -1);
        
    }
    var sortNumber = total.sort(compareFunc);
    function sai(array,num){
    var count =0;
    for(var i = 0; i<array.length; i++){
        if(array[i]<=num){
            num = num - array[i];
            count++;
        }
    }
    return count;
    }
    console.log(sai(sortNumber,str[0]));
