You know, now that I think about it...The description of the test was pretty incoherent. If I don't know what my test data is, and if the problem description is incoherent, I can't really make it work. It's also taking a metric fuckton of time to evaluate my solution. Which apparently fails. For reasons I can't debug because I can't see the test data. Any company that relies on code snippets, incomplete problem statements and undefined test data to judge coders will get what they deserve.

maybe there's more than one task, but the task i took appeared to be completely specified (the one where you find a balance point - i may have remembered the name wrong - for an array, so that the sum of elements to either side is equal). it wasn't obvious to me what to do on first read, but when i paid a little more attention, everything was there (including edge cases, as far as i could see). in particular, they gave a formal numerical expression that was unambiguous (and which didn't seem to contradict the text).

  Yep, it's good to read the specs in detail ;)

    The spec was clear, but the fact that the test dataset used for the test was the very one given as an example wasn't. plus, it was a bit frustrating not being able to fiddle with the test dataset. I would have done it locally with my compiler, but the necessary boilerplate would have lost me time. So, I didn't test enough, and made a silly error which went undetected because of the trailing zero. I still got 75%, but that looks quite miraculous. EDIT: It appears I can customize my test dataset, and I didn't see it. Silly me.

      Yes, it is even possible to add your own data sets, Codility will tell you what you code returns for them. I guess we should make it more apparent in the interface.
