I agree, having more examples would help with decoding while not taking away from the problem.

Voting kata grants additional honor points, but does not increase your kyu rank. You can advance your rank only by solving kata.

and after completing katas rate them
you will get 1 point for approved and I think 2 for betas

It's not what is meant by copying and pasting being problematic in context of Codewars. Working in local IDE is perfectly OK, and by some (for example me) strongly recommended way of working with kata.

If you use your account to read the kata, grab the initial solution and tests from the trainer, solve the kata in your IDE and then paste it back into the trainer to submit, it's perfectly fine, you do not need to retype anything.

Not that copy/pasting was meant.That was about copy/pasting of other user's solution from internet or codewars.

I recently read that codewars frowns upon copying and pasting code when solving Katas. I've been coding in Jupyter Notebooks to test my work then copying it into codewars before testing/submitting. Does this affect my ranking? If so I will definitely start re-typing my code into codewars to avoid this.

what is the right data format? I know my logic is correct but it fails for n > 60
