WebApr 17, 2024 · In a Binary Search Tree (BST), all keys in left subtree of a key must be smaller and all keys in right subtree must be greater. So a Binary Search Tree by definition has distinct keys and duplicates in binary search tree are not allowed. WebSo your algorithm to find duplicates only identifies 99, beacuse you only check if a child node of a node has the same value as the node self. Note the successor of a node in a subtree is the outer left node of its right child and the predecessor is … WebApr 3, 2024 · Problem Statement: Given a sorted array with possible duplicate elements. Find number of occurrences of input ‘key’ in log N time. The idea here is finding left and right most occurrences of key in the array using binary search.

WebMar 21, 2024 · The brute force approach of this problem to find the maximum count of duplicate nodes in a Binary Search Tree is to hash all the node values of the bst in the map. After that, we will traverse the map and store the node with the maximum hash value in a variable because the hash value equals the count of nodes in the bst. Algorithm WebA simple way to find out if the trees has two nodes that have same data value is to traverse the tree and store the value in an Array List and then checking if the Array List has any …
