Simple Array Sum

Abstract

Given an array of integers, find the sum of its elements.

Simple Array Sum#

Note

This was adapted from the Hacker Rank challenge available here.

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 in the editor below. It must return the sum of the array elements as an integer.

simple_array_sum has the following parameter(s):

  • list(ar) an array of integers

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#

\(0<N,ar[i]\le1000\)

Output Format#

Print the sum of the array’s elements as a single integer.

Sample Input#

6
1 2 3 4 10 11

Sample Output#

31

Explanation#

We print the sum of the array’s elements: \(1 + 2 + 3 + 4 + 10 + 11 = 31\).

Python Solution Docs#

A simple module that prints the sum of an array of integers.

Assignment

— Complete the simple_array_sum function below.

The function is expected to return an INTEGER. The function accepts INTEGER_ARRAY ar as parameter.

simple_array_sum.simple_array_sum(ar_list)#
