// Now that we have the while loop set up, it's time to compute the sum! Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.
For example: sum = sum + newValue. Or you could use the compound addition operator sum += newValue where newValue is the value retrieved from the array.
let numbers = [2,8,1,16,4,3,9] var sum = 0 var counter = 0
while counter < numbers.count {
print(numbers[counter])
counter += 1
}
let numbers = [2,8,1,16,4,3,9]
var sum = 1
var counter = 0
// Enter your code below
while counter < numbers.count {
print(numbers[counter])
counter += sum
}
var results: [Int] = []
for multiplier in 1...10{
results.append(multiplier * 6)
}

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