I struggle a lot in graph and tree problems.. Can anyone pls suggest how can I improve and any problemset or questions I may try to solve? Thanks in advance.. Don't downvote.. Plz help me out..

I am very annoyed by the fact that no matter how much I try I can't even cross the pupil barrier.. Now everyday or in every two days I am going to past here the problems I am solving.. If I don't slv any problem I can update the post.. Maybe this will help me in pushing myself everyday..any newbie or pupil or even higher rated coder can do the same or slv the porblems I am posting here.. I will slv it no matter what if I can't then watch the edi and slv somehow but will solve everyday for sure.. I think I will start doing cses again first.. Hope for the best..

N.B. I am not bluffing I am pretty much serious about it so pls dont write anything hateful that will demotivate me. Thanks :D

How can lgms always speedrun the problems a to d to in div2 no matter how hard the problems are?!? They also just ace any div3 or div4 contest..I know it's practice but it amazes me how everytime even if the initial problems are hard for many they still somehow manage to do that quickly.. That's pretty impressive.. Maybe someday I can do at least 10 percent of that :)
