Data Structures and Algorithms The Complete Masterclass - Binary Search

The video tutorial introduces binary search, emphasizing the need for a sorted array as a prerequisite. It explains the binary search algorithm, highlighting the process of finding the middle element and comparing it to the target. The tutorial uses examples with pointers to demonstrate the algorithm's efficiency. It discusses conditions for updating pointers and concludes with a preview of the next lecture on implementation and complexity.

What steps would you take to implement binary search in a programming language?

Can binary search be applied to unsorted arrays? Why or why not?

How do you handle the case when the left pointer exceeds the right pointer in binary search?

What is the expected time complexity of the binary search algorithm?
