MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Binary search is a recursive algorithm. The high level approach is that we examine the middle element of the list. The value of the middle element determines whether to terminate the algorithm (found the key), recursively search the left half of the list, or recursively search the right half of the list.

Detailed explanation-2: -One of the most fundamental algorithms in computer science is the Binary Search algorithm. You can implement Binary Search using two methods: the iterative method and the recursive method. While both methods have the same time complexity, the iterative method is much more efficient in terms of space complexity.

Detailed explanation-3: -The major difference between the iterative and recursive version of Binary Search is that the recursive version has a space complexity of O(log N) while the iterative version has a space complexity of O(1). Hence, even though recursive version may be easy to implement, the iterative version is efficient.

Detailed explanation-4: -In a linear search, each element in the list is searched one after the other in a sequential manner until it is found in the list. A binary search, on the other hand, finds the list’s middle element recursively until the middle element matches a searched element.
