WebBinary search 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 sorted array, if they are unequal, the half in which the target cannot lie is eliminated and the search continues for the remaining half until it is successful. WebBinary search is a search algorithm that finds the position of an element (target value) within a sorted array. It is also known as half-interval search or logarithmic search. Important Points i) Always use binary search with sorted values (either in asc or desc order). Bubble sort algorithm and their implementation
