Sfida di programmazione: Sum an Array

Problema

Return the total of all numbers in the list. An empty list sums to 0.

Implement sum_array(numbers).

numbers: The list of integers.

Return the sum.

0 ≤ length ≤ 100,000; the total fits in a 64-bit integer

Esempio 1

Input:
numbers = [1, 2, 3, 4]

Output atteso:
expected = 10

Input:
std::vector<long long> numbers = {1, 2, 3, 4};

Output atteso:
long long expected = 10;

Input:
long[] numbers = new long[] {1, 2, 3, 4};

Output atteso:
long expected = 10;

1 + 2 + 3 + 4 = 10.

Esempio 2

Input:
numbers = []

Output atteso:
expected = 0

Input:
std::vector<long long> numbers = {};

Output atteso:
long long expected = 0;

Input:
long[] numbers = new long[] {};

Output atteso:
long expected = 0;

Nothing to add: 0.
