Hi Brian,
First, I really enjoy this tutorial and want to thank you.
I did the challenge of this part using this function :
func largest() → Self.Generator.Element{
var largest: Self.Generator.Element? = nil
for item in self {
if largest < item{
largest = item
print(“The largests is now (largest)”)
}
}
return largest!
}
But you did it in a different way and I’d like to know the best practices in that case :
func largest() → Generator.Element {
var index = startIndex
var largest = self[index]
while index != endIndex {
if largest < self[index] {
largest = self[index]
}
index = index.successor()
}
return largest
}
Thanks in advance and kind regards
