See Alexandrescu’s Fastware talk on how amazingly sentinels can improve even textbook algorithms, and how to apply the approach intelligently. E.g., for a linear search, overwrite the last element with the sought after value, and do a tiny bit of work to make that safe and to undo it before return. If you’re skeptical, I really do encourage you to watch, he’s not sloppy. [VIDEO]
