Don't post solutions in Discourse, please.

Love this one!

After 3 months tried again and solved somehow. xD It's not that hard, but you need to know how Date works.

It's just such a simple solution and at the same time very clever !!!

A lot of us using unnecessary computing power before remembering that this little formula existed, this is why maths are important!

I never saw your message ('cause, spoiler flag)...

No, afaik, there's no difference aside of, maybe, the readability. What you suggest will most likely be a little faster, but since it's computed one time only, no real interest.

In any case, tastes and colours, yeah.

Resolved.

LOL

This is genius.

One option is to use C# to its fullest power and write a custom LINQ extension method that transforms any multidimensional array to a jagged one.

@hobovsky: My 2 cents: It's not just LINQ. There aren't that many languages with multidimensional array support like C#. The original kata and all other translations expect a jagged array as output. IMO the translation is not consistent with the original (and the other translations) without a good reason.(*) The output format limits the possible ways to solve this kata or forces using some unusual tricks.

(*) When C# supports jagged arrays and jagged arrays are the usual way, what is the point of using a construct specific to C# which is not consistent with the original? ¯\_(ツ)_/¯
