The idea here is finding left and right most occurrences of key in the … WebAug 23, 2024 · If during insert we find a node that duplicates the key value to be inserted, then we have two options. If the application does not allow nodes with equal keys, then this insertion should be treated as an error (or ignored). If duplicate keys are allowed, our convention will be to insert the duplicate in the left subtree.

BST is also referred to as ‘Ordered Binary Tree’. In BST, all the nodes in the left subtree have values that are less than the value of the root node.
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 Web1 day ago · I am a beginner in C++ and I have a task to delete duplicate elements in a balanced binary tree using a pre-order traversal. I might be able to do this in a binary search tree, but I have no idea how to implement it in a balanced tree. Can someone provide guidance or advice on how to do this or provide a function for processing the 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).
WebChapter 25 Binary Search Trees A __________ (with no duplicate elements) has the property that for every node in the tree the value of any node in its left subtree is less than the value of the node and the value of any node in its right subtree is greater than the value of the node.
