FAQs
Question: What is the main advantage of using Binary Search over Linear Search? Answer: The main advantage of Binary Search is its efficiency; it reduces the time complexity to O(log n) compared to O(n) for Linear Search, making it much faster for large datasets.
Question: Can Binary Search be used on unsorted arrays? Answer: No, Binary Search requires the array to be sorted beforehand; otherwise, it will not function correctly.

Q. If the target value is not present in the array, what will binary search return?
A.
The index of the closest value
B.
The index of the first element
C.
The index of the last element
D.
-1
Solution
If the target value is not found, binary search typically returns -1 to indicate absence.
