    Would it be interesting to add a batch of relatively small random tests that also output N on error, just to give users an idea in which phase of their algorithm their mistake is? Or is the fact this Query is a total black box part of the difficulty level and challenge of this kata?

    I've added smaller tests

    nvm, I probably made a mistake in calculations

    Integer precision should be perfect up to about 4000 digits, which calculations in my kata shouldn't exceed. Maybe you're accidentally using floats somewhere? That's strange, if you're not

    I don't understand Python, I thought integer precision was infinite:

    And random tests of smaller numbers first too. Massive numbers are basically undebuggable.

    Random tests are horrible. No meaningful error output, just one big blob of tests. Split these tests into batches and give some proper error feedback.

    ok, who knows if it's impossible to cheat on this kata but it's definitely a lot more difficult now
