Given an array of integers, find the sum of its elements.
For example, if the array ar = [1, 2, 3] 1 + 2 + 3 = 6 so return 6.
Function Description
Complete the simple Array Sum function with the following parameter(s):
- ar[n] an array of integers
Returns
- int: the sum of the array elements
Input Format
The first line contains an integer, n. denoting the size of the array.
The second line contains n space-separated integers representing the array's elements.
Constraints
0 < n, ar[i] <= 1000
Sample Input
STDIN Function
----- --------
6 ar[] size n = 6
1 2 3 4 10 11 ar = [1, 2, 3, 4, 10, 11]
Sample Output
