I don't understand , am I not eligible to ask questions because I am not a specialist or expert? Few minutes ago I asked for help regarding a topic. Just asked for some resources which help me learn that stuff. I asked this because I feel that Watching some random videos on that topic won't help.

However I am receiving downvotes for asking question? I really can't get this . Was there something wrong in the question? It is not that I have not tried understanding that topic. I have watched EDU section and read CSES cp handbook . I tried a lot but still can't get the idea that's why I asked it on codeforces. Random downvoting should end. It is really frustrating.
