I can't answer to challenges's questions 😞😞
what can I do ?
If you don't know the answer to a question you can take a screenshot and try to find the answer after the challenge. Try to understand the code and run it. Search for solutions on the internet. This way you will learn from the challenges, too.
Is this supposed to be a bug report or do you simply don't know the answers?
because I not learned it in sololearn I need some ext référence
Me too I cannot answer some questions. So what did I do? Learn the parts slowly that I missed or cannot answer. Don't force yourself to learn everything within one day. Take time, and be patient. With over time, your skills will improve. :) don't think too much bro. Don't go for challenges yet.
