array-sum

Instructions

Write a function that takes an array of numbers and returns the sum of all the numbers in the array.

• If the array is empty, the function should return 0.

Expected function

func ArraySum(numbers []int) int {
    // your code here
}

Usage

package main

import (
    "fmt"
)

func main(){
    fmt.Println(ArraySum([]int{1,2,3,4,5}))
    fmt.Println(ArraySum([]int{}))
    fmt.Println(ArraySum([]int{-1,-2,-3,-4,-5}))
    fmt.Println(ArraySum([]int{-1,2,3,4,-5}))
}

and the output should be:

$ go run . 
15
0
-15
3
