WebSo what Parallel Binary Search does is move one step down in N binary search trees simultaneously in one "sweep", taking O(N * X) time, where X is dependent on the problem and the data structures used in it. Since the height of each tree is Log N, the complexity is O(N * X * logN) → Reply. himanshujaju. WebReason — In a case where the search item is at the first place in a sorted array, sequential search becomes faster than binary search as the first comparison yields the desired value. In case of binary search, the search value is found after some passes are finished. For example, let us consider an array arr [] = {2, 5, 8, 12} and the search ... dr. wingo ocala floridaWebAnswer (1 of 4): When you talk about “faster” with respect to specific algorithms, most answers will involve the “average case” performance when N, the number of elements, is very large.
