989 PointsI can't figure out what they want me to do in this code challenge, how should I approach this? Challenge Task 2 of 2
Working with Loops, Challenge Task 2 of 2
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
}
while counter < numbers.count {
sum = sum + numbers[counter]
counter++
}

operator is depreciated :(
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}

counter++
This is no longer available since swift 3. You should do like this:
counter += 1
Also in this line:
sum = sum + numbers[counter]
You could do like this:
sum += numbers[counter]
I hope that helps.
