Binary Search

This lecture introduces the binary search algorithm, emphasizing the need for a sorted input array. The instructor explains the binary search process, comparing it to linear search, and demonstrates how to find a target value by iteratively narrowing down the search range using middle elements. The lecture includes examples with pointers and discusses conditions for updating pointers. The session concludes with a brief mention of the algorithm's complexity, hinting at logarithmic behavior, and sets the stage for the next lecture on implementation and complexity analysis.
