Courses Plus Student 2,845 PointsHow to use the value of counter using a var index to compute the sum of the values in the array?
I tried to use the unary operator += to .count to prevent to loop to running infinitely. Please help!
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
index += counter
}

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
var index = (counter - 1)
sum = numbers[index] + sum
}
print(sum)
