## AI overview

A tutorial explaining binary search, an efficient algorithm for finding an item's position in a sorted array by repeatedly halving the search range. It covers the requirement that the array be sorted, the search steps, and use cases including checking values, finding occurrences, and determining insertion points.

## Source excerpt

I wrote a small interactive book to teach binary search.
