Swift 3 Collections and Control Flow - operators.swift

I'm stumped on this one, shouldn't I use modulo for this one?

operators.swift 
var results: [Int] = []

for n in 1...100 {
    // Enter your code below

    // End code 
}

Hey Gabriel,

Yep, you are correct in that you will need to use the Modulo function.

So... here are some hints for you:

  • The challenge gives you a hint too, in telling you that you will need to use the negation operator to check for uneven numbers: If n % 2 == 0 gives you the even numbers that using != will give you the odd numbers.
  • To check for numbers divisible by seven is the same as checking for even numbers, but use 7 instead of 2.

I will leave the if statement and appending to the array up to you, but I think you should be okay now. If you still are stuck, just leave a comment here.

Keep Coding! :dizzy:
