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. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again … WebA Binary Search would require the data to be sorted in O(nlogn) and then searched O(logn). Therefore, the time complexity would be O(nlogn) + O(logn) = O(nlogn). Case 2: When the data is sorted, a Binary Search will be more time efficient as it will only take O(logn) time, while the Sequential Search will still take O(n) time. howdens solihull contact numberWebTo apply binary search on an unsorted array, First, sort the array using some sorting technique.
