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

For example, if the array , , so return .

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, , denoting the size of the array. 
The second line contains  space-separated integers representing the array's elements.

Constraints

Output Format

if __name__ == '__main__':
    fptr = open(os.environ['OUTPUT_PATH'], 'w')

    ar_count = int(input())

    ar = list(map(int, input().rstrip().split()))

    result = simpleArraySum(ar)

    fptr.write(str(result) + '\n')

    fptr.close()
