WebFeb 18, 2024 · In the tree data structure, traversal means visiting nodes in some specific manner. There are nodes2 types of traversals. Generally, this kind of traversal is based on the binary tree. A binary tree means each node can have a maximum of 2 nodes. A binary tree is a well-known data structure. There’s also a Binary Search tree (BST).

WebSep 7, 2024 · Breadth-First Search (also Level Order) This one is a little more tricky and can only be done using a queue. It might be possible with recursion but it's easier to understand iteratively. It uses a queue when traversing so it goes through the tree as nodes are added to it. As a result, it goes through the tree, level by level. WebGiven below is the algorithm of Preorder Traversal: Step 1: Visit the root node. Step 2: Traverse the left sub tree, i.e., traverse recursively. Step 3: Traverse the right sub tree, …
