The video tutorial introduces binary search, emphasizing the need for a sorted array. It demonstrates setting up a binary search example using Spring Boot, focusing on understanding tight and loose coupling. The tutorial walks through implementing a binary search method, running the application, and decoupling sorting logic. It concludes by discussing how to dynamically switch between sorting algorithms like bubble sort and quick sort, highlighting the importance of loose coupling in software design.

Why is it important to return the index of the found element in a binary search?

What changes would be necessary to switch from bubble sort to quicksort in the binary search implementation?

Describe how you would implement a bubble sort algorithm as a separate class.
