The "dancing links" implementation seems to me too tricky as the "algorithm X" built-in backtracking already implies a lot of unlink and relink operations between nodes to cover or uncover the same rows and columns in the way.

That's why I preferred implementing links, but with a simpler rows and columns handling.
