WebSep 1, 2024 · What is a Binary Search Tree? A binary search tree is a binary tree data structure with the following properties. There are no duplicate elements in a binary search tree. The element at the left child of a node is always less than the element at the current node. The left subtree of a node has all elements less than the current node. WebA Binary Search Tree (BST) is a binary tree in which each vertex has only up to 2 children that satisfies BST property: All vertices in the left subtree of a vertex must hold a value smaller than its own and all vertices in the …

Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.
