We agree, solving binary search tree problems do not need solving. That's an old problem. Problem is if you need people to choose and adapt algorithms for a specific new problem, copilot will have a hard time and so you will have a hard time if you don't know how the algorithms work and never adapted one. Because copilots are not good at choosing the correct algorithm and adapting it for new problems, as far as my experience with the competitive programming course I took goes anyway.

If you have an old problem, copilot can solve it, true.
