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).

Web1.1 Binary Search Trees Problem: Figure out the rank of a node in O(logn) time. You may use augmentation. The rank of a node is its position in a sorted list of the nodes. Solution: We keep the number of children in a node’s right and left subtree (denoted as R(n) and L(n)) as an augmentation. To nd the rank of a node x, we begin with r = 0. WebFeb 16, 2024 · Example 3. # Write a Python program to find out the rank and element in the program. class new__nod: def __init__ (self, record): self.record = record self.Lft = self.Rt = None self.LftSize = 0 # We are now inserting a new node in the list. def insert (root, record): if root is None: return new__nod (record) # We have to update the size of the ...
WebApr 28, 2016 · If key < node key, go left and continue to search. If key > node key, go right and continue until key == node key value. At each step, you increment the level you have gone (your rank I presume) until you have a match. If you don't find a match, then the rank should be -1 (not found).
