I have a variable that contains an integer number with the condition that the number 0 (zero) in the variable is a separator between one number and another. The numbers will be separated and sorted based on the numbers in the numbers themselves. After that, the ordered numbers will be bined again without a separator with the output in the form of an integer number.

So example:

dividerSort(74108520159);

the output I want is 147258159

but my output is: 112455789

This is so far I try, hope you can help me figure out

function dividerSort(num){
    const divider = 0     
        let getNum = Array.from(String(num), Number)     
        getNum = getNum.filter(item =>{         
                return item !== divider   
         })
        getNum = getNum.sort()
        getNum = getNum.join('');
        console.log(getNum);
}
dividerSort(74108520159);

• 1 You keep using “number” when you mean either “number” or “digit”. – RBarryYoung Commented Nov 21, 2020 at 18:48

Sorted by: Reset to default 12

function dividerSort(num){
  var result = '';
  var items = num.toString().split('0'); // items = ["741", "852", "159"]
  items.forEach( item => {
    result = result + item.split('').sort().join('') // see Explanation
  });
  console.log('Result: ', result);
}
dividerSort(74108520159); // Result:  147258159

Explanation: forEach() item in items split at every charachter item.split(''). Example: "741" bees an array ['7', '4', '1']. This array can be sorted simply with Array.sort() so it bees ['1', '4', '7'] which will then be joined back together to a string with Array.join() . At every iteration concatenate the result to result...

You could split the string with zero, map splitted substrings with splitted by chcaracter, sort them and join them. Then join the mapped part strings.

function dividerSort(num){
    return +String(num)
        .split('0')
        .map(s => s.split('').sort().join(''))
        .join('');
}

console.log(dividerSort(74108520159)); // 147258159

you can use String.split() method to split.

usage

let number = 1230456098;
let stringified = number.toString(); // to use String.split ()

let splitted = stringified.split("0"); // ["123", "456", "98"]

// convert those "string" elements of `splitted` array into numbers, and then apply sorting algorithm.

splitted = splitted.map(split=>parseInt(split));  // [123, 456, 98]

TLDR;

1. convert that integer to a string, using Number.toString(),
2. use String.split() to split the string,
3. map through the splitted array and convert those string elements into numbers, using splitted.map(split=>parseInt(split));

function dividerSort(num){
  return `${num}`.split('0').map(x => x.split('').sort().join('')).join('0')
}

We can use split() method for acplish this. We just need to pass 0 as separator and sort them. After sorting, we can join them using join() method.

function divideAndSort(n){
  var result = '';
  var items = n.toString().split('0'); // items = ["741", "852", "159"]
  items.forEach( item => {
    result = result + item.split('').sort().join('')
  });
  console.log('Result: ', result);
}
divideAndSort(74108520159); 
// Result:  147258159
