Not sure how to retrieve an index value from an array that is a constant? Very confusing and not covered in the material leading up to this question?
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while sum >= 7 {
counter += 1
sum = sum
}

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
}
