As title, did Codefights remove 1-on-1 challenge? I cannot find that feature anymore. I search on google but no information.
Does anyone here use Codefights experiences ?
Sorry and please skip this post if you don't use Codefights.
I also ask on Codefights. Link
Yes they did. You can read their rationale, or comment on it, here.

Thank you very much indeed for your answer
