Rejected due to no random tests

never saw abs before) thanks

• Adds edge tests.
• Improves feedback of failed tets.
• Fixes some names.

added random tests

Both functions have the same functionality and end result, but I think my implemenation is more readable, making it easier to maintain and debug.

The use of the "for" loop makes the code more straightforward and eliminates the need for advanced string manipulation techniques, making it the better choice in my opinion.

Can anybody explain why it works? Because after = threre is a Boolean expression?

I did not expect someone to actually respond, none the less in such an educational and constructrual manner. Thank you for the references and articles. I've been going through Paul Hudson's course works and I haven't come across him actually talking about this outside of the linked article which seems relatively new compared to everything else.

Again, thank you!

Yes this is possible. It is mentioned in Swift Documentation. See the 1st link below.

As far as I know, there is no official code style guide provided by Apple so I can't tell you for sure whether it is standard or best practice. According to above mentioned documenation it is opportunity rather than obligation.

Just my experience:

• I've been taught to omit "return" in one-liners at the iOS course
• Paul Hudson and John Sundell has similar articles about it, but they say "you can omit..."

I think this is the subject for regulation in particular company.

• https://docs.swift.org/swift-book/LanguageGuide/Functions.html
• https://www.swiftbysundell.com/questions/when-can-the-return-keyword-be-omitted/
• https://www.swiftbysundell.com/tips/omitting-the-return-keyword/
• https://www.hackingwithswift.com/quick-start/understanding-swift/when-is-the-return-keyword-not-needed-in-a-swift-function

1. Didn't know you you had the choice to no use the "return" keyword for one-liners.
2. Is this actually considered standard or best practice?

Here you have an explanation how format works.
https://docs.python.org/2/library/functions.html#format
"b" returns value in binary format.

can sb explain pls???

Please, investigate n = 2256.

The document has many sections. Would you be precise to which one you are referring? Thx.

Hi there! Is is possible for you to explain this line of code in a bit more human way? I am still very new to Swift and I would like to understand what actually does this abs, reduce(1,*) :)) Thanks in advance for that!
