FAQs

Question: What is the main advantage of using Binary Search over Linear Search?
Answer: The main advantage is that Binary Search has a time complexity of O(log n), making it significantly faster than Linear Search, which has a time complexity of O(n), especially for large datasets.

Question: Can Binary Search be applied to unsorted arrays?
Answer: No, Binary Search requires the array to be sorted beforehand; otherwise, it will not function correctly.

Question: How can I improve my understanding of Binary Search algorithms?
Answer: Regular practice with MCQs and case studies, along with reviewing the algorithm's theory, will enhance your understanding and application skills.
