Maybe it’s like teaching kids the quadratic equation; where it’s less about learning the thing and more about understanding how to problem solve and use logic.
In this case maybe the point is to show an understanding of algorithms and that you can explain them out loud.
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.
Thank you.
"I don't have to know CS201 Data Structures and Algorithms to do my job", says a thousand D-tier coders online, whose code is costing their employers a small fortune in unnecessary cloud compute bills because they just blindly imported a ton of python libraries and went with the least suitable data structures and algorithms for the task at hand, because that's what the defaults were for that library. "It fulfils all the requirements from the client perfectly, bow to my experience and skill in delivering customer value".
It's classic Dunning-Kruger, incompetent people who are too incompetent to know they're incompetent.
Bonus points when they cite the fact that they were involved with a project that cost a hundred million dollars, as "proof" that they're a world-class expert, when it probably would have been a ten million dollar project with an actually competent engineer...
