in Ruby

1. sample tests are broken, they have even syntax errors
2. style issue: function name coveredDots should be covered_dots
3. attempt tests expect strange non-integer results. e.g. 987.5909072547386 × 943.3982221769694 ↺ 73° 1240171 ̷≈ 931691.5061422606

very nice and concise! thanks for sharing!

in JS sometimes generateCoords generate illegal moves (a self-capturing move, for example) and a test (for instance, "Rollback more than amount of moves raises an error") could fail with a correct solution.
I was lucky to observe it at least once
maybe that could be fixed (or, at least, it could be mentioned in description that test could have some unstable behaviour)

random test cases are inconsistent between langauges: JS tests only lowercase letters but in Ruby there are uppercase letters as well

spetacular solution in calc increasing fifty!

thank you!

still wasn't enough, but I forced it, approved!

changed, unfortunately still not enough. :( Wrote to Ulrich asking him to provide a feedback because I am almost sure that he can help with it.

I think the standard deviation in ranking feedback is currently too high. Change your 4 kyu vote to 5 and I bet it'll become approvable.

thanks.

yes, it is still in "Ranking feedback needed" state

good kata, unfortunately, my vote and rank is still not enough to make it approvable :/

Fixed. TY for your contribution.

Interesting.. let me look into this. Thanks for finding it.

Fixed for the first one.. will need to look into the second. Thanks for finding this.

in JavaScript I've got such an input in random tests:

{ width: 5, height: 3 }
[
  [ { x: 1, y: 1 }, { x: 3, y: 1 } ],
  [ { x: 3, y: 1 }, { x: 2, y: 2 } ],
  [ { x: 1, y: 2 }, { x: 1, y: 0 } ],
  [ { x: 1, y: 2 }, { x: 1, y: 1 } ]
]

and it tells expected false to equal true
but when I copied it to sample tests picture clearly shows me that there are no partitions and my answer (false) seems to be correct
