WebJun 23, 2024 · Binary search algorithm falls under the category of interval search algorithms. This algorithm is much more efficient compared to linear search algorithm. Binary search only works on sorted data structures. This algorithm repeatedly target the center of the sorted data structure & divide the search space into half till the match is found. WebTo perform a binary search array must be sorted, it should either be in ascending or descending order. Step 1: First divide the list of elements in half. Step 2: In the second step we compare the target value with the middle element of the array. If it matches the middle element then search ends here and doesn’t proceed further.
