WebCan you solve this real interview question? Balance a Binary Search Tree - Given the root of a binary search tree, return a balanced binary search tree with the same node values. If there is more than one answer, return any of them. A binary search tree is balanced if the depth of the two subtrees of every node never differs by more than 1. WebIn computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes.Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, except for the root node, which has no parent. These constraints mean there are no …

Web11 de ago. de 2024 · AVL trees are called as balanced binary search trees because they maintain a balance factor at each node which is the difference between the heights of the left and right subtrees. This balance factor is used to ensure that the tree remains balanced and provides efficient search operations. 4. WebA balanced BST is a Binary Search Tree in which the left and right subtrees differ in height by no more than 1. A binary tree can be rebalanced to become a balanced BST, thereby ensuring that all subtrees of a given node will differ in height by no more than one (1).
