Hello community,
I have been on this platform for a while now but one thing which I can’t understand that what is it when you a see a question tells you, “Aha, a graph question!”, or something like, “What better than a fenwick tree?”. And after that how do you start with the implementation. I have hardly any experience with graph question and that’s one major reason why I am lacking behind. Any application based resources would be appreciated, thanks!
