I haven't done a code review for a while, but today, I'm reviewing some code sent to me by Nikhil, who was wondering about how best to generalize his timing analysis of some sorting algorithms.

In this video, I take a run at it, giving you an example of finding a common interface and replacing one-off code with array and loop-based alternatives. This result is, I think, a cleaner and more general setup for testing these sorting functions. I also look a little at the simple correctness tests included in the code.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.


About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.
