Hi, thanks for taking the time to look at my problem. I'll make changes later.

I don't quite understand you. Can you show me an example?

Hi in dart there are tuples and there is a fixed array, what are these data structures for in this task?

The test headers were taken from python solution during translation

No, that's a bug. Fixed it. Thanks.

I removed the backwards-compatibility from the sample tests and made the author's solution static. I am on the fence about removing it altogether. On the one hand, I do not like invalidating valid solutions with a change of interface, on the other hand I am aware that it should not get in the way of upgrading things and making interfaces more idiomatic.

I can update it if you want, I usually do not alter it when patching old katas, to make sure I did not break anything.

erratum: the "kumite published with failed tests" can be bypassed for either of the test suites ("Test Cases" / "Sample Test Cases") by selecting the other test suite when publishing. that way, the other suite will be the one run against the solution when "publish" validates the code, and by the "View Run Output" button

this is still kind of a hack though

yes, but if the author's solution does not pass the sample tests, the kumite is "published with failed tests" and i'm not sure whether such kumites are approvable. i did not alter the author's solution, to make sure old solutions still work.

proposed fork also solving the other 2 C# issues

please, the snake case again ..

Looks good - thanks!

i fixed everything. the input array is now const-qualified. the tests do not alter it. it is printed upon failure. no more UB in the test suite. there is still a reference solution though, because i found it easier than generating the array from the answer.
