## A Very Big Sum

In this **HackerRank** **A Very Big Sum problem solution** In this challenge, you are required to calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large.

## Function Description

Complete the aVeryBigSum function in the editor below. It must return the sum of all array elements.

aVeryBigSum has the following parameter(s):

int ar[n]: an array of integers.

**Return**

long: the sum of all array elements

**Input Format**

The first line of the input consists of an integer n.

The next line contains n space-separated integers contained in the array.

**Output Format**

Return the integer sum of the elements in the array.

## Solution (Base on how i solved it)

```
$bigNum = 0; //variable to hold results
$myarr = sizeof($ar); //counted how many field i have in the given array
for($i = 0; $i < $myarr; $i++){ //loop through the given array
$bigNum += $ar[$i]; //add each field to my result variable
}
return $bigNum; //here is my result
```
