How’s do I retrieve values from inside the while loop?
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
}

sum += numbers[counter]
or something similar to assign the value to the variable. Since it was created outside of the loop, it's accessible outside the loop. Does that help or make sense?
