If it's about problem solving and using logic, why do we need to memorize quicksort? That's not an example of using logic or problem solving
You don’t need to memorize quicksort. If you understand how it works, it’s trivial to work out the exact details.
you can also 'trivially' derive the quadratic formula using completing the square, but does anybody actually do that instead of just memorizing the formula?
Honestly, for the first year or two after learning about it (which is the only time where it's really relevant) that's exactly what I did. Spend 30 seconds, derive something that's definitely correct, and never worry again about your memory randomly failing you
