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.
Now is the perfect time to enhance your understanding of Searching Algorithms! Dive into our practice MCQs and test your knowledge on Binary Search, ensuring you are well-prepared for your upcoming exams.
Q. If an array contains 32 elements, how many iterations will binary search take in the worst case?
A.
4
B.
5
C.
6
D.
7
Solution
For an array of 32 elements, the worst-case number of iterations is log2(32) = 5.
Q. What is the time complexity of binary search in the worst case scenario?
A.
O(1)
B.
O(log n)
C.
O(n)
D.
O(n log n)
Solution
In the worst case, binary search will continue to halve the search space until it finds the target or concludes it is not present, resulting in O(log n) time complexity.
