> Being a self taught software developer who has been programming since I was 12, I had no idea how to reverse a binary tree. I fail to see the link between the premise and conclusion here. I'm also largely self taught and been programming since childhood. And although I also did go to a university to study math, most of what know about algorithms is from self-learning to satisfy own curiosity, not from attending university courses. University gave me a chance to participate in ACM ICPC and paid for my flights a few times, for that I'm grateful - I was able to land a FAANG job right out of school thanks to my success at it. But they did not teach me algorithms and competitive programming, that was all self study.
