Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.
I have this from 1st task so far:
let numbers = [2,8,1,16,4,3,9] var sum = 0 var counter = 0
while counter < numbers.count { counter += 1 }
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter < numbers.count {
counter += 1
}

let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
