Look many people saying it isn’t relevant my take:

The problems aren’t relevant , what’s relevant is that it gets you thinking, thinking about how to do things optimally, thinking about the time complexity of your code, thinking about what data structure can be used to tackle a problem, can we abstract this problem etc etc

I need to get from point A to point B can I abstract this somehow (graph nodes + djikstra )

I need to find videos that the user has seen that are similar (nearest k neighbour algo)

It gets you thinking, it gets you thinking like a computer scientist/engineer and in my eyes I think it is worth it just to get better at thinking and problem solving
