I'm disappointed by the lack of effort in this kata Mr Hilla284, do better next time.

You unfortunately stripped all the interesting stuff of the kata, by providing the grid to the user.

If you don't find it interesting to do a cipher challenge with an encryption key, why would you do the kata? Why are you acting like providing a key to a user for a challenge is so unreasonable?

Now, all that's left is a straight and simple replace X with Y task, for both function. Which makes your kata a duplicate of any other associated task.

What are you talking about? ALL ENCRYPTION KATAS ARE REPLACE X WITH Y TASKS - THAT'S WHAT ENCRYPTION IS. Yet funnily enough, I still see cipher challenges and more "replace X with Y tasks" everywhere on this site.

Btw, we already have several kata about polybius square encryption.

Yes we do, but I made my square work in many dimensions, and be passed as a parameter, unlike others which use a key and are based of the standard 2d latin square. Besides, this is incredibly hypocritical from you, considering you've made a "perfomance edition" of the Ulma Sequences task, which you can basically copy and paste one solution from there to another.

What doesn't it have to do with the title? It's a Polybius Square Cipher because of it's coordinate encryption system and it's "Multidimensional" since the encoding grid isn't limited strickly to 2 dimensions as it usually is.

Changed so that when n=0 → (None, None) is the solution, and when n=1 → (l, None) is the solution. I did this since my maths teachers couldn't decide what it would be and also due to the little amount of information of the topic on the web. If you can provide me with that says something otherwise as well as citing a credible source online then I promise you I will change it immediately.

Sample Tests are now the same as Fixed Tests

Done! Now there are 5 fixed tests: 2 tests with 1 frame, different sizes and no speed; 1 test with 3 frames and no speed; and 1 with 2 or greater size, speed and frames.

What do you mean? Can you give a specific example?

I was told to make it return a tuple not an array by you and @dolamroth, also I was told by you to generate more random test cases, as such all the solutions are now invalid. Do you think I should revert my changes, I'm kinda new to this.

its fixed now!

Thanks for letting me know
