Really highlights the divide between industry and acedemia.

Reminds me of when another subreddit was mocking some legacy code (I think Motorola? Some mobile device stuff) for using bubble sort. Meanwhile, the sort probably wasnt on more than a fee hundred items and the mobile embedded is constrained for space. Bubble sort is easy to read, write and has O(1) space. Performance isn't a concern at the scale being worked at. We're talking maybe microseconds of difference.

It's not necessarily a bad thing that acedemia focuses on theory. But we keep using school to put a square peg into a round hole and wonder why students are so unprepared for actual production.

It's ultimately the company's fault. If you want certain skills, you need to train for it. Your processes aren't public, so you can't just expect candidates to magically know what matters to their role.

now acedemically: the answer is to swap an item to the end and reduce the buffer size. I don't think that's taught in acedemia either, but that's a trick you learn on the job. When and if you do need it.
