Hello cf users I was looking for a problem to solve, but finding an interesting problem can take a while, especially in the graph tag In addition to being time-consuming, this work also causes boredom So, if you see an interesting question that was average and had nice ideas on graphs tag, I would appreciate it if you share it so that both I and others can use it :)
