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.

What are the key differences between linear search and binary search?

How can the binary search algorithm be implemented in a programming language?

Explain the steps taken when the target is not found in the binary search.

What is the time complexity of the binary search algorithm and why?
