WebNov 11, 2024 · A binary tree is balanced, if, for every node, the heights of its left and right children differ by at most 1. If a node doesn’t have any of the children, then the height of the absent children is -1. Let’s have a look at these two trees: In the tree on the left, nodes of a height 2, marked in red, make this binary tree unbalanced.

WebA "binary search tree" (BST) or "ordered binary tree" is a type of binary tree where the nodes are arranged in order: for each node, all elements in its left subtree are less-or-equal to the node (<=), and all the elements in … In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree. The time complexity of operations on the binary search tree is directly proportional to the height of the tree.
