![]() ![]() ![]() Here is how the depth-first search will traverse the tree starting from root node. In DFS, we go as deep as possible down to one path before we explore or visit the different node or the next sibling (It’s like a maze you go to one end before exploring other side). The depth-first search (DFS) is a tree traversal technique. In this article we will focus on the binary tree traversal using depth first search. Breadth First Search or Level Order Traversal. ![]() On a high level, we have the following 2 options for binary tree traversal in Java. Binary tree is non-linear data structure, and it provides few different options for traversal. We start from the beginning and move through each element. Arrays, Linked list etc), we have only one logical way to traverse through them. Binary Tree Traversalīinary tree traversal differs from the linear data structure. Java-SE1703: Vector, TreeSet, HashSet, TreeMap, HashMap 1. ![]()
