 Queue
diff --git a/q3.swift b/q3.swift
 //Queues are structured such that the first job in is the first job out (or done/printed in this case). A stack would print the last job entered into it first. And a hashmap is a bit too elaborate for this job.

 Hashmap
diff --git a/q5.swift b/q5.swift
 //A hashmap would be ideal as it pairs values and keys together, so the artist name could be the key and their albums could be the songs.

 Array
diff --git a/q7.swift b/q7.swift
 //An array, or more specifically, a Set would be the best for picking a name at random as the raffle numbers would be stored without an order and it would be easier to pick one at random (i.e., print out the set and pick the first one).
