Problem Statement

Loop through and print each element in a collection in order. Use your language's "for each" loop if it has one, otherwise iterate through the collection in order with some other loop.

Let's start with the solution:

for i in [1,2,3] {
   print(i)
}

for i in [1,2,3].Iterate() {
   print(i)
}

func myCollection() {
    yield 1
    yield 2
    yield 3
}

for i in myCollection() {
   print(i)
}
