Adding 1 in to each of array with Separators in javascript

Adding 1 to each in array from 1 to 15 maximum.
with Numeric Separators .

Code:

---

var n = "11_11_11_11_11_11_11_11_11_11";
var addone = "1";
var maxNum = "15";
var separator = "_";

function addNum(n, separator, addone, maxNum) {
    return result.join("_");
}

---

Result

Code:

---

... "11_11_11_11_11_11_11_11_11_12"
... "11_11_11_11_11_11_11_11_11_13"
... "11_11_11_11_11_11_11_11_11_14"
... "11_11_11_11_11_11_11_11_11_15"
... "11_11_11_11_11_11_11_11_12_1"
... "11_11_11_11_11_11_11_11_12_2"
... "11_11_11_11_11_11_11_11_12_3"

Is it possible to add a large numbers with Separators :confused:?

Split function puts the string into an array.

Join turns the array back into a string.

The rest of the logic seems quite simple - and maybe even recursive. Do you need to see finished code?

What have you got so far?

Hi :wave:

Code:

---

var n = "11_11_11_11_11_11_11_11_11_11";
var addone = "1";
var maxNum = "15";
var separator = "_";

function addNum(n, separator, maxNum) {
n = n.split(separator).reverse(); 
    let maxLen = n.length;
    let sum = [];
    let remainder = 0;

    for (let i = 0; i < maxLen; i++) {
      let x = parseInt(a[i]) ? parseInt(a[i]) : 0;
      let digit = (x + remainder);
      remainder = Math.floor((x + remainder));
      sum.unshift(digit);
    }
    if (remainder) {sum.unshift(remainder)}
   
    return sum.join("_");
  //return sum.filter(n => { return n; } ).join('_');
}

I have tried this function but it's not count up .:confused:..

@optikal - did you solve this yet?

Hi szlamany ,thank you for your attention.

I am working hard to solve it.
But It's not working yet with this function too :mad:
It's seems very very difficult...

Code:

---

function addNum(arr, separator, maxNum) {
    arr = arr.split(separator).reverse();
    let maxLen= Math.max(arr.length);
    let sum = [];
    let remainder = 0;
    for (let i = 0; i < maxLen; i++) {
      let x = parseInt(arr[i]) ? parseInt(arr[i]) : 0;
      let digit = (x + remainder) % 10;
      remainder = Math.floor((x + remainder) / 10);
      sum.unshift(digit);
    }
    if (remainder) {sum.unshift(remainder)}
   
    return sum.join("");
        //return sum.filter(n => { return n; } ).join('-');
}

---

This works for me:

Code:

---

function addNum(n, separator, maxNum, addone) {
    n = n.split(separator).reverse();
    let maxLen = n.length;
    let sum = [];
    let max = parseInt(maxNum, 10);
    let remainder = parseInt(addone, 10);

    for (let i = 0; i < maxLen; i++) {
        let x = parseInt(n[i]) ? parseInt(n[i]) : 0;
        let digit = (x + remainder);
        if (digit > max) {
            digit = 1;
            remainder = 1;
        } else {
            remainder = 0;
        }
        sum.unshift(digit);
    }

    return sum.join("_");
}

---

Tested with this loop

Code:

---

function testNum() {

    var n = "11_11_11_11_11_11_11_11_11_11";
    var addone = "1";
    var maxNum = "15";
    var separator = "_";

    for (var i = 0; i < 100; i++) {
        n = addNum(n, separator, maxNum, addone);
        alert(n);
    }

}

Cool code to write - thanks for the exercise!

BOOOM Thats it szlamany.
thank you for your time.
Cool:thumb:
