Binary Search Complexity

The video tutorial explains the complexity of binary search, highlighting its efficiency compared to linear search. It describes the binary search process, where an array is divided into halves to find a target element, resulting in a time complexity of log N. The tutorial compares this with linear search, which has a time complexity of O(N), emphasizing the efficiency of binary search. It also discusses best, worst, and average cases for binary search, concluding with a brief mention of the next lecture on implementation.

What are the best and worst case complexities of binary search?

How does the number of elements in an array affect the worst-case scenario in binary search?
