FAQs
Question: What is the time complexity of Binary Search? Answer: The time complexity of Binary Search is O(log n), making it much more efficient than Linear Search for large datasets.
Question: Can Binary Search be applied to unsorted arrays? Answer: No, Binary Search can only be applied to sorted arrays. If the array is unsorted, it must be sorted first.

Q. If a binary search is performed on an array of size 16, how many comparisons will it take in the worst case?
A.
4
B.
8
C.
16
D.
5
Solution
In the worst case, binary search will take log2(16) = 4 comparisons, but since we start counting from 0, it will take 5 comparisons.
