Algorithm Scaling and Reasonableness

The video tutorial explores the concepts of reasonable and unreasonable algorithms, focusing on their scaling properties. It compares binary and linear search algorithms, explaining how binary search is more efficient for large datasets. The tutorial also covers the AP board's criteria for algorithm reasonableness, highlighting polynomial and exponential scaling. A Code.org activity demonstrates these concepts, followed by practice questions to reinforce understanding.
