Sum of Array Elements
Easy Accuracy: 61.02% Submissions: 37342 Points: 2

Given an integer array arr of size n, you need to sum the elements of arr.

Example 1:

Input:
n = 3
arr[] = {3 2 1}
Output: 6

Example 2:

Input:
n = 4
arr[] = {1 2 3 4}
Output: 10

Your Task:
You need to complete the function sumElement() that takes arr and n and returns the sum. The printing is done by the driver code.

Expected Time Complexity: O(n).
Expected Auxiliary Space: O(1).

Constraints:
1 <= n <= 103
1 <= arri <= 104
