Quite a challenging kata to learn something new.

I love how tenacious you are :)

Approved

I added one example with 5 steps.

It should be clear that in order to get from step 1 to 5, there should be at least 4 instructions.

from say step 2 to 5 or 1 to 4, there should be at least 3 instructions.

from 1 to 3, 2 to 4, 3 to 5, 2 instructions.

you get my point? The graphs that I made have multiple examples within that are "subarrays" of the example with most instructions.

Interesting mathematical coding challenge, congratulations.

Been sitting for a while now. Tried everything I knew, even lagranges and legendres theorems (iterative reduction too), which work perfectly fine, passes all cases but takes a lot of time. Im failing with the timeout. Tip for others: Do not try to bruteforce and avoid deep recursion, takes a lot of resource and time so not efficient.

Great solution!

Nice mathematical coding challenge.

is this cheating though? 🤨

Yes, you need a complete rewrite of the program. Your current solution solves a 6 kyu problem, not a 1 kyu problem. I suggest you read articles about this problem online or in your local library.

This is a well known problem in Math, I suggest you read literature about it. It's a math heavy task.

great, but I have to add a spoiler tag for hinting at ways to solving a purple kata.
