A Very Big Sum HackerRank Solution in C, C++, Java, Python

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

simpleArraySum has the following parameter(s):

  • 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

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
