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. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch … WebApr 14, 2024 · Instead of calling your Binary Search Tree class a BST, define it as. class BinarySearchTree(object): # remainder of your code Gives more meaning to the class name.
