Can you just tell me the answer? I get the problem but not how to write the code?

I get what each thing does, but I dont seem to know how to write it out. Thanks.

loops.swift
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

// Enter your code below

while counter < 7 {
print("sum")
counter += 1
}

var sum += numbers[counter]

Your sum variable isn't in the while loop.

while counter < 7 {
print("sum")
sum += numbers[counter]
counter += 1
}
