• Hello, guys!
I am trying to solve the second task using JavaScript, but a couple of test cases I just can't pass.
Here you go, my code:

``````/**
* function ListNode(val) {
*     this.val = val;
*     this.next = null;
* }
*/
/**
* @param {ListNode} l1
* @param {ListNode} l2
* @return {ListNode}
*/
var addTwoNumbers = function (l1, l2) {
var number1 = getNumber(l1);
var number2 = getNumber(l2);
var sum = number1 + number2;
var list, temp;
var numberCount = getNumberCount(sum);

if (sum !== 0) {
while (numberCount--) {
if (list) {
temp = list;
}

list = new ListNode(parseInt((sum / pow(10, numberCount))) % 10);
list.next = temp;
}
}
else {
list = new ListNode(sum);
}

return list;
};

function pow(x, y) {
if (y === 0) {
return 1;
}
else {
var p = 1;
for (var i = 1; i <= y; i++) {
p = p * x;
}
return p;
}
}

function getNumber(array) {
var number = 0;
var i = 0;

while (array !== null && array.val !== null) {
number = number + array.val * pow(10, i);
array = array.next;
i++;
}

return number;
}

var getNumberCount = function (number) {
var i = 0;
while (number > 0) {
number = number / 10;
i++;
}
return i;
};
``````

For now, I cannot handle the following input:

``````[2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,9]
[5,6,4,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,2,4,3,9,9,9,9]
``````

Because I encountered scientific number and now I have to rewrite the method `getNumberCount()`.
Could you provide any ideas, how can I fit the fix into my current solution?

Thanks a lot!
