python new test framework is required. updated in this fork

Although there is a check for "Shouldn't change the input array," it is not enough

I thought I was going to have to skip this one, but when I started writing some notes down it started to come together, then some long forgotten linear algebra from about 10 years ago resurfaced. My solution probably isn't the best but it works. Excellent kata, very satisfying.

Nice!! I learned something new.

.

Thanks for finding these, I've updated methods within the reference solution to be defined, and added imports for everything used in the test cases. Also updated to use the new framework annotations and blocks, and moved the reference solution inside a 'random tests' block.

I would suggest to remove all hints in the description (maybe leave a note in the beginning).

No, high efficiency is a requirement, and I will not change the tests to allow slow code to pass.

In case you still wish to try solving it:

• "A little bit" is a huge understatement - normal tests are supposed to take up a small fraction of the alloted time (my solution takes < 500ms) but you can't even pass them
• Your solution always fails for high total produce values; I've updated the normal tests to catch such problems immediately
