Hello

I want to try training by reading hard problems and then reading their editorial immediately and implementing them did anyone try this training approach before.

Hello I have a question if I have a tree with n nodes and all nodes have some value there are two types of queries

1. what is the max node value in the path (u,v)

2. update u to be equal to x

I think HLD can solve this problem but I want to know if there is other ways or techniques that can solve a problem like this

Thank you

edit:

Why does eveybody keep downvoting I just had a question

I want to make a challenge for myself I want to reach candidate master in the next 2 months can you tell me an advice to make a plan to improve quickly

thank you

I try to be better in dp and saw so much videos and I am still not good in dp I try to solve problems but I find it hard to come up with a dp solution
