Binary Search


Linear Search


Either A or B


None of the above

Detailed explanation1: The binary search algorithm works on the principle of divide and conquer and it is considered the best searching algorithm because itâ€™s faster to run.
Detailed explanation2: Implementation of a Binary Search The most significant difference between the two methods is the Recursive Method has an O(logN) space complexity, while the Iterative Method uses O(1). So, although the recursive version is easier to implement, the iterative approach is more efficient.
Detailed explanation3: However, in the average case scenario, hash lookup is significantly faster than binary search. In real applications, we mainly consider an average case scenario in order to test and compare the performance of different methods. Therefore, hash lookup is a better choice in such cases.
Detailed explanation4: The main advantage of using binary search is that it does not scan each element in the list. Instead of scanning each element, it performs the searching to the half of the list. So, the binary search takes less time to search an element as compared to a linear search.
