binary search binary search algorithms and data structures course binary search in computer science, binary search is a search algorithm that finds the position of a target value within a sorted array. examples: seeking word in dictionary algorithms and data structures course binary search binary search compares the target value to the middle element of the array: if the target value matches the element, its position in the array is returned. if the target value is less than the element, the search continues in the lower half of the array. if the target value is greater than the element, the search continues in the upper half of the array. if the search ends with the remaining half being empty, the target is not in the array. by doing this, the algorithm eliminates the half in which the target value cannot lie in each iteration. algorithms and data structures course binary …
