WebIn computer science, a k-d tree (short for k-dimensional tree) is a space-partitioning data structure for organizing points in a k-dimensional space. k-d trees are a useful data structure for several applications, such as searches involving a multidimensional search key (e.g. range searches and nearest neighbor searches) and creating point clouds. k-d trees are … Web501. Find Mode in Binary Search Tree. Given 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. The left subtree of a node contains only nodes with keys less than or equal to the node's key.

WebBinary search tree is a data structure that quickly allows us to maintain a sorted list of numbers. It is called a binary tree because each tree node has a maximum of two children.
