WebNov 11, 2024 · The Average Case. In this case, the existing binary search tree is a balanced tree. Unlike the worst case, we don’t need to compare the new node’s value with every node in the existing tree: The existing binary search tree is a balanced tree when each level has nodes, ... WebOct 5, 2024 · The average time is smaller than the worst-case time, because the search can terminate early, but this manifests as a constant factor, and the runtime is in the same complexity class. Using a linear search in a sorted array as an example: the search terminates when a greater or equal element has been found.
WebOct 17, 2024 · binary search: average case is log n, best is 1 (middle item = desired item), and worst is log n (desired item not in list) selection sort: average case is n 2, best is n 2, and worst is n 2; selection sort: average case is n log n, best is n log n, and worst is n log n. The graphs may look like this: WebSo overall time complexity will be O (log N) but we will achieve this time complexity only when we have a balanced binary search tree. So time complexity in average case would be O (log N), where N is number of nodes. Note: Average Height of a Binary Search Tree is 4.31107 ln (N) - 1.9531 lnln (N) + O (1) that is O (logN).
