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. 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).
