• No random tests

• No sample tests
• No random tests
• It should be clear if this is a performance kata (up to 16 potions) or a simple kata with brute force solutions.

I also fail so see the difference from single-case handling in the example solution. If the batch processing is a design choice, the example solution should showcase that difference.

Noted! May you please provide any feedback on how to improve.

That would make sense if the additional performance were actually required, and mapping individual modpows over the list would timeout. Is it, and does it?

Good catch! I’ve now added a reference implementation of mod_power inside the test suite to avoid this error.
This internal function is only used to compute expected results and won’t affect user solutions.

You're absolutely right. This kata expects the user not to use pow() or **.
I'll make this restriction more explicit in the kata description, and update the tests if needed to catch such usage.
