Java Fork enforcing that the swapping is done in-place, to align with the other languages. the author's original solution still passes the tests, so correct solutions should be preserved.

Javascript looks ok.

At least in Java (my solution returns a brand new list only based on values). I don't know for JS, C requires in place mutation.

Is there any attempt to translate this kata into Python yet? Would allow more people to play. :)

The kata requires actually to return a linked list with swapped values, it doesn't check that the nodes from the input list have actually been swapped. It is not about writ(ing) a method that swaps each pair of nodes in the list (though it works too). The description could make this clearer.

Add tag Linked lists

Had a good time solving this kata, thanks
