Hello everyone. I need some suggestions on where to begin solving graph theory problems. I have read some books and articles and am able to program bfs, dfs, spanning tree problems etc. But when it comes to solving programming contest problems, I cannot solve any problem.
I mean in books, we have questions like "print nodes of a graph in bfs manner (graph in adjacency list or matrix)", but in programming contests,it is not the case.
I cannot even solve problems tagged easy. I was having similar problems in dp but now I can solve easy dp problems. But I am seriously lost in graph theory problems. Can anyone help me?
P.S. editorials tell logic of the problem but not how to solve them.Please give suggestions without any reference to editorials and wikipedia.
