WebGiven the root of a binary search tree (BST) with duplicates, return all the mode (s) (i.e., the most frequently occurred element) in it. If the tree has more than one mode, return them in any order. Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than or equal to the node's key. WebGiven the root of a binary tree, return all duplicate subtrees. For each kind of duplicate subtrees, you only need to return the root node of any one of them. Two trees are duplicate if they have the same structure with the same node values. Example 1: Input: root = [1,2,3,4,null,2,4,null,null,4] Output: [ [2,4], [4]] Example 2:

Find the maximum count of duplicate nodes in a Binary Search Tree

WebNov 16, 2013 · Remove duplicate algorithm for a Binary Search Tree: Start a tree walk (in/pre/post order) At each node, do a binary search on the subtree rooted at that node for the key value stored in the node. If the key value is found down the tree, call delete (key) and restart step 2 (Might have multiple duplicates). Webon a binary search tree should require O(h) time where h is the height of the tree. • It turns out that the height of a balanced binary tree is roughly log 2 (n) where n is the number of elements if the tree remains approximately balanced. • It can be proved that if keys are randomly inserted in a binary search tree, this condition will hp bagus dibawah 1 juta

Strategy to find duplicate entries in a binary search tree

WebA binary search tree is ordered, so duplicates are logically next to each other. So you just visit the nodes of the tree in order and the duplicates are all found in a single pass . That is straightforward and optimal so I don’t see a reason to consider any alternative algorithms. 3 1 Manohar Reddy Poreddy WebBinary Search Working. Binary Search Algorithm can be implemented in two ways which are discussed below. Iterative Method; Recursive Method; The recursive method follows the divide and conquer approach. The general steps for both methods are discussed below.
