Typing "how to reverse a binary search tree" into google is not the same thing as solving a problem.

If these problems were so reliant on individual problem solving ability, there wouldn't be dozens of books with reams of answers to these questions on the market. These questions test memorization and nothing else.

I mean, that's a little strong. My undergrad degree is in math, so I would be thrilled if I was sitting in an interview and was being asked questions like that instead of stuff about how computers actually work.
