I wish they would update the compiler, I got burnt on writing a Fortran Queue that makes use of allocatable data types. I wrote it in Visual Studio, but when I copied and pasted the code it the CodeWars compiler bounced back saying it did not support allocatabled data types.

That is:

TYPE QUEUE
INTEGER:: I
TYPE(QUEUE), ALLOCATABLE:: NXT
END TYPE

Resulted in the compiler complaining:

TYPE(QUEUE), ALLOCATABLE:: NXT

is not allowed when it is part of the Fortran 2008 Standard

I think my solution correctly gives the "brute-force functions" requested in Task 1. Now I've seen other solutions the 2nd task is superfluous.

But what happened to n being "relatively small"?

Seriously. The description makes it seem like the algorithmic complexity isn't a factor. I would have approached this problem completely differently if I'd known the "relatively small" n would timeout. A bit frustrating to be honest, especially considering how many comments are pointing this out.

Thanks!

A nice little problem that was fun finding the optimal code!
I'd just say that the numerical examples are necessary to sort out e.g. when c0 is taken.

@Phil157 If you are stuck with the Fortran version of this Kata, feel free to post your code here and mark it as a spoiler so I can review it and perhaps provide some feedback, cheers :)

I think this output issue is due to the Fortran CW-2 testing framework itself. I'll look into improving its output by replacing special characters (such as newlines) with their escape sequence equivalents (e.g. \n) in my spare time.

I had a random test (data = 5864, 8410, 1193, 1.5) fail with a value just below x.5000 (in both my Fortran & Excel) being rounded UP to x + 1, so I added a halfpenny!

I am asking @donaldsebleung to see your posts (he is the Fortran translator).

Outputs are different through languages.
"(3(A, I0), A)" is good practice.

In your instructions the example output, ["M: f", "B: b", "C: c"], should not have any " or , !

I see the other 2 solutions write results with format "(A, I0, A, I0, A, I0, A)", is "(3(A, I0), A)" not good practice?

Hi, I'm still stuck like my last post - sorry to send it on a weekend, I realised almost immediately after hitting "Post".

Try a different zoom level - I've just posted on a very similar problem.
