Finally, the algorithm recursively sorts the subarrays on the left and right of the pivot element. WebSep 27, 2024 · The Binary Search algorithm works as follows: Set the search space equal to the sorted array Take the middle element of the search space and compare it to the target value. - If the target equals the middle element, you have found the target value. Return the index of the middle element and terminate the function. organic girl dressings reviews
