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. WebBinary search is the most efficient searching algorithm having a run-time complexity of O (log 2 N) in a sorted array. Binary search begins by comparing the middle element of the list with the target element. If the target value matches the …
