MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Binary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you’ve narrowed down the possible locations to just one.

Detailed explanation-2: -In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array.

Detailed explanation-3: -Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half. The idea of binary search is to use the information that the array is sorted and reduce the time complexity to O(Log n).

Detailed explanation-4: -Search algorithms can be classified based on their mechanism of searching into three types of algorithms: linear, binary, and hashing.

Detailed explanation-5: -Binary search works on the divide and conquer approach, i.e. the list from which the search is to be done is divided into two halves, and then the searched element is compared with the middle element in the array. If the element is found, then the index of the middle element is returned.
