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: -Binary search works on sorted arrays. Binary search begins by comparing an element in the middle of the array with the target value. If the target value matches the element, its position in the array is returned.

Detailed explanation-3: -Binary search is a fast search algorithm with run-time complexity of (log n). This search algorithm works on the principle of divide and conquer.

Detailed explanation-4: -Binary Search is a searching algorithm for finding an element’s position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array. Binary search can be implemented only on a sorted list of items. If the elements are not sorted already, we need to sort them first.

Detailed explanation-5: -Interpolation and Quadratic Binary Search. If we know nothing about the distribution of key values, then we have just proved that binary search is the best algorithm available for searching a sorted array.
