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 .

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

**Output Format**

Return the integer sum of the elements in the array.

**Constraints**

**Sample Input**

```
5
1000000001 1000000002 1000000003 1000000004 1000000005
```

**Output**

```
5000000015
```

**Note:**

The range of the 32-bit integer is .

When we add several integer values, the resulting sum might exceed the above range. You might need to use long int C/C++/Java to store such sums.
